STEWART, J.
Defendant Kawan Hasimrashid Hardy was convicted after a jury trial and sentenced to 19 years and 8 months in prison on five criminal counts for firing a semi-automatic pistol in the direction of an occupied vehicle while standing in the street on 90th Avenue in Oakland, California one evening in September 2018. An Oakland Police Department undercover officer observed Hardy firing a handgun of some kind, which was corroborated by a liquor store's surveillance video and other evidence.
Most of Hardy's sentence was based on his conviction for assault with a semi-automatic firearm (count 5), it having been designated the principal term among multiple counts. The strongest, and only unambiguous, evidence that the firearm he fired was a semi-automatic was an audio recording that had been sent to the Oakland Police Department by a third-party service called "Shotspotter."
In the published part of this opinion, we conclude the trial court erred in admitting the Shotspotter evidence without first conducting an evidentiary hearing to assess its scientific reliability pursuant to People v. Kelly (1976) 17 Cal.3d 24, 130 Cal.Rptr. 144, 549 P.2d 1240, which in turn relied on Frye v. United States (App.D.C. Cir. 1923) 293 F. 1013 (collectively Kelly / Frye ). We further conclude the error was prejudicial and therefore reverse Hardy's conviction on count 5.
In People v. Cowan (2010) 50 Cal.4th 401, 113 Cal.Rptr.3d 850, 236 P.3d 1074, our Supreme Court noted that, while Kelly relied on Frye , it has become more appropriate to refer to Kelly alone because the United States Supreme Court has ruled that the Federal Rules of Evidence superseded Frye . (Cowan , at p. 469, fn. 22, 113 Cal.Rptr.3d 850, 236 P.3d 1074.) We refer here to the "Kelly / Frye " rule because that is the designation used below and in this appeal by the parties.
In the unpublished parts of this opinion, we discuss Hardy's arguments for reversal of his conviction for willfully and maliciously discharging a firearm at an occupied vehicle (count 1). First, Hardy contends that the preliminary hearing magistrate committed prejudicial error by improperly barring defense counsel's cross-examination of the undercover officer about the officer's location at the time he observed defendant fire the weapon, which the magistrate ordered under Evidence Code section 352 after the officer claimed an official privilege under Evidence Code section 1040 to withhold the information. We conclude that, assuming error for the sake of argument, it was harmless. Hardy also argues the trial court committed instructional error in responding to a jury question during deliberations about this count. We conclude this claim lacks merit.
BACKGROUND
In October 2018, after the Alameda County District Attorney filed an amended criminal complaint against Hardy regarding the September 2018 shooting incident, and after a preliminary hearing, the magistrate ordered that Hardy be held over on certain charges. Consistent with the magistrate's ruling, the district attorney filed an information charging Hardy with four felony counts: discharge of a firearm at an occupied motor vehicle ( Pen. Code, § 246 ; count 1 ), possession of a firearm by a felon (§ 29800, subd. (a)(1); count 2), carrying a loaded firearm in a city (§ 25850, subd. (a); count 3), and possession of ammunition by a prohibited person (§ 30305, subd. (a)(1); count 4). On the first day of trial, the court allowed the prosecution, over a defense objection, to file an amended information that added count 5, which alleged Hardy had also committed an assault with a semi-automatic firearm in violation of section 245, subdivision (b), with an enhancement for personal use of a firearm under section 12022.5, subdivision (a).
All further statutory references are to the Penal Code unless otherwise stated.
At trial, evidence was presented that on the evening of September 14, 2018, members of the Oakland Police Department's Crime Reduction Team (CRT) engaged in undercover surveillance of the area around Booker's Liquor Store (store), which was located at the corner of 90th Avenue and Olive Street in Oakland. About 20 people were gathered in the store's parking lot, which abutted both 90th and Olive, for the making of a music video. Undercover officer Gregory Rosin was the "point officer" with the best view of the scene, and Officer Joseph Coleman was the supplemental undercover officer positioned a little further away. The surveillance operation began at about 7:30 p.m.
Officer Rosin was the prosecution's principal trial witness against Hardy. Rosin testified that he surveilled the scene from inside a parked car on 90th Avenue across the street from the store, using his eyesight alone and binoculars. His vantage point allowed him to "watch[ ] what was happening in front of me and to the sides of me" and gave him "a clear and unobstructed view of this scene." He could see the store's parking lot, the store building, traffic passing him on 90th Avenue and traffic going up and down on Olive Street up to a little past the store's driveway. He was in radio communication with Officer Coleman and several uniformed CRT members, the latter being located in marked patrol vehicles a few blocks away.
During the surveillance, Officer Rosin recognized from previous contacts Hardy and two others, DeMarcus Wilson and David Grant, in the area of the parking lot. Hardy was wearing a black hooded sweatshirt and distinctive black pants with white stripes running down the sides. Wilson was wearing a red hooded sweatshirt, and Grant was wearing a white T-shirt. At about 8:20 p.m., Rosin noticed Hardy, Grant, and Wilson separate themselves from the larger group in and around the parking lot of the store and walk to the corner of Olive and 90th Avenue. He had a clear and unobstructed view of the three from about 45 to 50 feet away. They remained at the corner for four or five minutes, walked back towards an Isuzu Rodeo parked near the store's entrance, and returned to the corner about two to three minutes after that. They stood on 90th Avenue, a four-lane street (with two lanes running in each direction) that had a stop sign just past the Olive Street intersection. Officer Rosin watched Wilson closely because he believed Wilson was armed based on bulges in his clothing and his movements.
A short time later, a white sedan traveling north on 90th Avenue drove by in the "number two" lane, the lane closest to where Hardy stood. Hardy "sprinted" into the "number two" lane looking north, crouched over, slowed his pace, took a "handgun" out of his clothing, extended it "out towards the white car" and began firing it "immediately after" the white car had passed him, meaning "one to three seconds" afterwards. He went 10 to 15 feet into 90th Avenue, and also advanced north 10 to 15 feet on 90th Avenue. Officer Rosin saw the gun's muzzle flash and heard "six or seven" shots. The record contains no evidence that anyone was hit by the shots, or that any property damage resulted from them.
Officer Rosin could not see the firearm that Hardy used. He acknowledged that revolvers make a muzzle flash when fired. Nonetheless, he testified he knew Hardy fired a semi-automatic weapon because Hardy fired "six or seven" shots and a revolver could only fire "five or six" shots, and because Rosin saw bullet casings on the ground after Hardy left, which he directed officers to collect. Rosin recalled that he saw the spent casings lying in the street, and on the grassy and paved areas of the sidewalk.
The record—meaning photographs and testimony by an Oakland Police Department evidence technician—indicates that investigating police recovered six .380-caliber bullet shell casings on the grassy and paved areas of the sidewalk, at the corner of 90th and Olive, but not in the street. The street was searched and no casings were found there. Police also seized a firearm from the Isuzu parked by the liquor store. An Oakland Police Department laboratory report admitted into evidence refers to the spent casings found on the sidewalk as "six fired 380 Auto caliber cartridge cases" that "have the same class of firearm produced marks and sufficient corresponding individual microscopic marks to conclude that they were all fired by the same firearm." The report further concludes, and the parties stipulated, that these casings were not fired from the semi-automatic weapon seized from the Isuzu.
Two Oakland police officers, Officer Coleman and Officer Patrick Airoso, also testified, both as lay persons based on their own extensive experience, about semi-automatic pistols and revolvers. Officer Coleman testified that spent casings are automatically ejected from semi-automatic pistols, in his experience always from the right side, whereas spent casings must be manually removed from revolvers. Officer Airoso testified that for right-handed semi-automatic pistols, spent casings are automatically ejected to the right and for left-handed semi-automatic pistols, spent casings are automatically ejected to the left.Officer Coleman was shown the six bullet shell casings found at the scene and asked if by looking at them he was able to tell the type of weapon they were fired from. He said it was "hard to read," but "you could tell based on the size and the print on the back what size bullet they are. And so what size the gun was chambered for. You can also tell—you'll be able to see what are called ejector marks. Those are when a semi-automatic pistol cycles through, there's actually a metal piece called an ejector that basically shoots out the spent casing. It catches it and shoots it out. So these will have a mark that's indicative of that." Also, he explained that "a semi-automatic would eject the spent casings, which then, unless the person who fires the weapon ... picks them up, are going to be left on the scene. That's one of the biggest pieces of evidence a semi-automatic will leave behind. It doesn't mean the revolver won't leave that behind. It just means the person would have to reload the revolver and dump the casings there." Coleman testified that he had fired "[a] dozen, two dozen" semi-automatic pistols, and that all of them ejected casings three to ten feet from a port on the right side of the weapon, and that none had ejected casings from the left side.
As for the events around the shooting, Officer Rosin further testified that, when the shooting started, Grant started walking down Olive Street towards the main group in and around the store's parking lot, while Wilson ran behind Hardy, removed a handgun from his waist and pointed it in the same direction as Hardy but did not shoot. After the shooting, Hardy and Wilson also walked back towards the main group. Wilson joined the group, but Hardy and Grant passed the group, continuing to walk down Olive towards 92nd Avenue, and were soon out of Officer Rosin's view.
Officer Rosin further testified that he radioed the other officers to tell them Hardy had fired a gun at someone. Rosin described Hardy's clothes and said he believed Wilson was also armed. Then, he said, within 10 to 20 seconds of observing Hardy fire the shots, he received a Shotspotter phone notification and audio recording informing him that shots were just fired at his location. Rosin testified that the recording, which he listened to at the scene, was "consistent" with what he observed.
As we will discuss, Shotspotter is a service used by the Oakland Police Department that sends officers notifications and audio recordings of sounds the service has identified as gunshots detected in certain areas of Oakland. The prosecution played the Shotspotter audio recording for the jury during Officer Rosin's testimony and at the beginning of closing argument. It consists of seven distinct percussive sounds, one right after the other, which were purportedly recorded at the time when, and the place where, Officer Rosin observed Hardy fire.
Surveillance footage taken from the liquor store, which was magnified, and without sound, was shown to Officer Rosin. He testified that the car in which he was sitting that night could be seen on the video, and he pointed out a white car. The video shows this white car parked across 90th Avenue, directly opposite the corner of 90th Avenue and Olive. The video also shows an individual wearing black pants with white stripes walk over to that corner with two others and shows the three then standing there together for about two minutes. A white sedan travelling north can be seen passing the three individuals on 90th Avenue in the lane nearest where the three were standing. The sedan slows to a near stop (around where Rosin testified there was a stop sign) and continues on as the individual in the striped pants hurries into the street, moving in the same direction as the sedan that has just passed by him and into an area of the video frame where he is partially obscured. Two flashes, one immediately after the other, appear just to his right, about head high. As soon as he hurries into the street, one of the other two individuals starts walking down Olive Street, followed a few moments later by the other, who is followed a few moments later by the person wearing the white striped pants. The three return to the area of the store parking lot, where the larger group is gathered. One of them joins the group, while the person wearing the white striped pants and the other individual continue walking down Olive Street until they are out of the video's lower right frame. A little more than four minutes later, the person wearing the white striped pants can be seen returning to the area of the store parking lot after apparently walking back up Olive Street.
Officer Coleman testified that on the night of the incident he was surveilling the area from a vehicle on Olive Street about a block away. He could not see all the way up to the corner of 90th and Olive, but he heard "around" six gunshots just before 8:30 p.m. He then heard Officer Rosin report that Hardy had shot at a passing vehicle and saw Hardy, Wilson and Grant, whom he recognized from previous contacts, walking quickly eastbound on Olive Street. Wilson stayed near an area of the liquor store parking lot that was on Olive some distance down from 90th Avenue (the surveillance video shows this as well), but Hardy and Grant continued on down Olive Street and turned onto 92nd Avenue, passing within 10 to 15 feet of Coleman's undercover vehicle. Coleman believed, based on Hardy's movements, that he had a firearm in his waistband. A few minutes later, Coleman saw Hardy and Grant walking back toward the liquor store.
For safety reasons, Officer Rosin waited about 15 minutes before calling in uniformed police officers to investigate at the scene while he remained undercover. The officers arrested Hardy at the liquor store. He was wearing a black hooded sweatshirt and black pants with white stripes down the sides, and was unarmed.The jury found Hardy guilty on all charges. The court imposed a total sentence of 19 years and 8 months, consisting of an aggravated term of 9 years on what the court designated as the principal conviction, which was on the count 5 charge of assault with a semi-automatic firearm, with an aggravated 10-year enhancement for personal use of a firearm. The court imposed and stayed a seven-year sentence on count 1, for the willful and malicious discharge of a firearm at an occupied vehicle, and imposed and stayed eight-month sentences on count 3 and count 4, all under section 654, and sentenced Hardy to a consecutive 8-month term on count 2.
Hardy timely filed a notice of appeal. DISCUSSION
Hardy argues his convictions on count 1, for discharge of a firearm at an occupied motor vehicle, and on count 5, for assault with a semi-automatic firearm, must be reversed. We conclude his count 5 conviction must be reversed because the trial court prejudicially erred by failing to conduct an evidentiary hearing, as requested by Hardy, to determine the reliability of the Shotspotter evidence as proof of the number of shots fired. We affirm his conviction on count 1.
I.
Hardy's Assault with a Semi-automatic Firearm Conviction Must Be Reversed.
Hardy was charged in count 5 with assault with a semi-automatic firearm. The Shotspotter evidence consists of the audio recording of seven percussive sounds and Officer Rosin's testimony that he received a notification from Shotspotter shortly after observing Hardy fire "six or seven" shots, which evidence Rosin testified was "consistent" with his observations. The recording is the strongest, and only unambiguous, evidence that Hardy fired more shots than can be fired from a revolver, which the evidence indicates can only fire up to six shots. Hardy argues the trial court's admission of the Shotspotter evidence without conducting an evidentiary hearing to determine whether such evidence is reliable was prejudicial error under Kelly / Frye .
A. The Relevant Proceedings Below
1. Hardy's Motion in Limine
Before trial, Hardy filed a motion in limine to exclude the Shotspotter evidence. Among other things, he argued the Shotspotter evidence was inadmissible under Kelly / Frye because the company's "process regarding gunshot identification and location has not been accepted by the general scientific community," and requested an evidentiary hearing under Evidence Code section 402. He contended the prosecution could not meet its burden of showing the technology's scientific acceptance because it had not designated any expert to testify about it. The prosecution did not file a written opposition to the motion.
During a break in the prosecution's presentation, the court held a hearing on Hardy's motion. After an apparently off-the-record discussion, the court said it was inclined to admit the Shotspotter audio recording, including because the prosecutor was "not going to claim it to be a gunshot as opposed to backfire or anything else." Defense counsel argued it was inadmissible hearsay. The prosecutor responded that he would introduce it merely to show why certain investigating Oakland police officers responded to the scene of the shooting and that, used for this purpose, it was not testimonial in nature and its authenticity went to its weight rather than its admissibility. "I'm not purporting it to be shots," he said. "I'm using this essentially, if the Court does think that it's hearsay, it's essentially the effect of [sic ] the listener as to why are these officers responding to this area?" He added, "Additionally, I think it goes to corroborate from what Officer Rosin [the undercover officer who saw Hardy fire a handgun from a car across the street] essentially on-views on that night," and then referred again to the evidence being relevant to why the officers went to the scene.
The court asked the prosecutor why someone from Shotspotter could not testify about the audio recording. The prosecutor replied that he had just gotten the report from Shotspotter the previous week, and that he would introduce the evidence through Officer Airoso, who "gets a Shotspotter notification and goes essentially to [the scene]," and not through the "surveilling officer."
Defense counsel responded that the Shotspotter evidence lacked foundation, and repeated his contentions, made first in his written motion, that an Evidence Code section 402 hearing should be held and that the evidence, without expert testimony confirming the scientific reliability of the underlying technology, was inadmissible under Kelly / Frye .
Without further explanation, the court then ruled that it would admit the Shotspotter evidence.
2. The Prosecution's Use of the Shotspotter Evidence
Contrary to his representation at the motion in limine hearing, the prosecutor did not introduce the Shotspotter evidence through Officer Airoso, although he called Airoso as his next witness. Instead, over Hardy's continuing objection on the same grounds as his motion in limine, the prosecutor introduced the Shotspotter evidence through Officer Rosin, the undercover officer who had surveilled the scene on the night of the incident from a car parked on 90th Avenue across from the store.
Instead, Officer Airoso testified that he was part of an arrest team supporting the undercover operation and went to the store about 30 minutes after Officer Coleman radioed that a third party going in and out of a silver Isuzu appeared to have a firearm.
Specifically, after Rosin testified that he saw Hardy fire "six or seven shots" in the direction of a white sedan traveling north on 90th Avenue, the prosecutor asked him about Shotspotter. Rosin said it was "technology that we have in Oakland that we use that detects the sound of gunfire," but that the police department did not operate it. It was "designed to give us gunfire that has just occurred," and gave "a detailed description of where it happened at and how many rounds were fired. It also sends us an audio clip so we can listen to the gunshots." He had used Shotspotter "multiple times a day" throughout his career, receiving its notifications via an application on his phone.
Officer Rosin further testified that he received a Shotspotter notification on the night of the incident about "ten or 20 seconds" after he saw Hardy fire six or seven shots. The notification provided him with the number of shots fired, the location and time of the shooting, and an audio recording, which he listened to when he received it. After listening to the recording at trial, he said it was "consistent" with what he observed and heard that night.
After Officer Rosin testified, the defense moved for a mistrial on the ground that admission of the Shotspotter evidence violated Hardy's due process rights. The court interrupted defense counsel's argument to comment that counsel had already been heard on the subject, and denied the motion. Later, the court also overruled the defense objection to the admission of the audio recording.
In closing argument, the prosecutor repeatedly referred to the Shotspotter audio recording for the truth of what it contained. He played the recording at the beginning of his argument and asserted it showed Hardy had fired seven shots, then repeated this assertion a short time later. The prosecutor also argued, apparently based on Rosin's testimony, that Rosin received a Shotspotter "activation" and "notification" on the night of the incident that indicated seven shots were fired at the location. After the defense argued there was no direct evidence that Hardy had fired a semi-automatic weapon, including because "[w]e didn't hear any evidence" on the audio recording, the prosecutor contended that "[t]he Shotspotter is circumstantial evidence that seven shots rang out at that time and location," and reminded the jury of the evidence that a revolver could not fire more than six shots. During its deliberations, the jury sent a note to the court asking to review the Shotspotter audio recording.
B. Analysis
1. The Court Erred in Admitting the Shotspotter Evidence Without Holding a Kelly / Frye Hearing.
The trial court denied Hardy's motion in limine without conducting an evidentiary hearing to determine whether Shotspotter's technology meets the standard of scientific reliability required under Kelly / Frye , although the defense requested such a hearing. The court's initial ruling is not necessarily incorrect because at the motion in limine hearing, the prosecutor represented that he would introduce the Shotspotter evidence not for the truth of what it contained but through Officer Airoso simply to explain why certain police officers responded to the scene of the incident. If the prosecutor had done as he said he would, the only question would have been whether the police received the notification, not what the Shotspotter evidence showed, and no Kelly / Frye hearing would have been required.
But the prosecutor did not introduce or use the Shotspotter evidence in the manner he had represented he would. He did not simply ask Airoso about it to show why some of the officers went to the scene; nor did he use it for that purpose. Instead, he introduced the Shotspotter evidence through Officer Rosin, who was already present at the scene when the incident occurred, and the trial court did not instruct jurors that there were any limits on the purposes for which they could consider it. Rather, the court summarily overruled Hardy's continuing objections to the prosecution's introduction of the evidence through Rosin, made on the same grounds as asserted in his motion in limine, including Kelly / Frye , and denied Hardy's motion for a new trial and overruled his objection to the admission of the Shotspotter audio recording without hearing any additional argument. These rulings required, and now require, a different analysis than the court's initial ruling. We must determine whether, when the prosecutor introduced the Shotspotter evidence through Officer Rosin for the purpose of proving that Hardy fired seven shots, which could only mean that he used a semi-automatic firearm, the court should have revisited whether Shotspotter's technology met the Kelly / Frye standard.
Under Kelly / Frye , " ‘when faced with a novel method of [scientific] proof,’ " our Supreme Court requires " ‘a preliminary showing of general acceptance of the new technique in the relevant scientific community’ before the scientific evidence may be admitted at trial." ( People v. Daveggio and Michaud (2018) 4 Cal.5th 790, 831, 231 Cal.Rptr.3d 646, 415 P.3d 717.) As our Supreme Court has also instructed, "Because the inventions and discoveries which could be considered ‘scientific’ have become virtually limitless in the near-70 years since Frye was decided, application of its principle has often been determined by reference to its narrow ‘common sense’ purpose, i.e., to protect the jury from techniques which, though ‘new,’ novel, or ‘ "experimental," ’ convey a ‘ "misleading aura of certainty." ’ " ( People v. Stoll (1989) 49 Cal.3d 1136, 1155-1156, 265 Cal.Rptr. 111, 783 P.2d 698.) In other words, Kelly / Frye " ‘is intended to prevent lay jurors from being unduly influenced by procedures which seem scientific and infallible, but which actually are not.’ " ( Daveggio and Michaud , at p. 831, 231 Cal.Rptr.3d 646, 415 P.3d 717.)
Kelly / Frye involves "a three-pronged test to establish the reliability of scientific testing and its scientific basis to determine its admissibility. ‘The first prong requires proof that the technique is generally accepted as reliable in the relevant scientific community. [Citation.] The second prong requires proof that the witness testifying about the technique and its application is a properly qualified expert on the subject. [Citation.] The third prong requires proof that the person performing the test in the particular case used correct scientific procedures.’ " ( People v. Lucas (2014) 60 Cal.4th 153, 244, 177 Cal.Rptr.3d 378, 333 P.3d 587 ( Lucas ), disapproved in part on another ground in People v. Romero and Self (2015) 62 Cal.4th 1, 53, fn.19, 191 Cal.Rptr.3d 855, 354 P.3d 983.) The proponent of the evidence has the burden of satisfying each prong. ( People v. Roybal (1998) 19 Cal.4th 481, 505, 79 Cal.Rptr.2d 487, 966 P.2d 521.) There is "no clear definition of science" under Kelly / Frye . ( Lucas , at p. 223, 177 Cal.Rptr.3d 378, 333 P.3d 587.) "Accordingly, the application of that term is guided by resort to the ‘narrow "common sense" purpose’ behind the rule: ‘to protect the jury from techniques which ... convey a " ‘misleading aura of certainty.’ " ’ ... The analysis is designed to address ‘scientific evidence or technology that is so foreign to everyday experience as to be unusually difficult for laypersons to evaluate.’ " ( Ibid . )
We must first determine whether Shotspotter's technology was of such novelty to the pertinent scientific community and our courts as to require Kelly / Frye analysis. Our Supreme Court has instructed that the Kelly / Frye standard "applies to that limited class of expert testimony which is based, in whole or part, on a technique, process or theory which is new to science and, even more so, the law. The courts are willing to forgo admission of such techniques completely until reasonably certain that the pertinent scientific community no longer views them as experimental or of dubious validity. This all-or-nothing approach was adopted in full recognition that there would be a ‘ "considerable lag" ’ between scientific advances and their admission as evidence in a court proceeding." ( People v. Stoll (1989) 49 Cal.3d 1136, 1156, 265 Cal.Rptr. 111, 783 P.2d 698.) In addressing defendant's Kelly / Frye argument, the trial court should have analyzed whether Shotspotter's technology, in whole or part, is a technique, process or theory which is sufficiently novel to science and, even more so, the law, so as to require Kelly / Frye review. Our review of the case law indicates that it is. Only two reported cases in California, both in our appellate courts, have even mentioned Shotspotter, both briefly and in 2019, and neither addressed whether Shotspotter evidence met the Kelly / Frye standard for reliability and therefore should have been admitted. (See People v. Coneal (2019) 41 Cal.App.5th 951, 955 & fn. 3, 254 Cal.Rptr.3d 653 [describing Shotspotter as "an acoustic gunfire detection and location system" that "has a 25-meter margin of error," and stating when and at what location Shotspotter identified certain numbers of gunshots fired]; People v. Rubio (2019) 43 Cal.App.5th 342, 345, 256 Cal.Rptr.3d 612 [Shotspotter, described as a "system" that "detects and triangulates the location of gunfire via microphones deployed throughout the city," notified officer of bursts of gunfire, causing him to respond to location where witnesses corroborated they had heard gunfire].) Even beyond California, we have found only one reported case in the country that has considered whether Shotspotter's technology was reliable enough to support admission of Shotspotter evidence of gunshots, a 2014 state court case from Nebraska, State v. Hill (2014) 288 Neb. 767, 851 N.W.2d 670 ( Hill ).
In Hill , the defendant was convicted of a murder in Omaha, Nebraska based on evidence that included a 2012 Shotspotter report of gunfire at a particular time and place. Before trial, the defendant moved in limine to exclude this report, including because Shotspotter's methodology was not scientifically valid. ( Hill , supra , 288 Neb. at pp. 770, 774, 851 N.W.2d 670.) The trial court conducted a hearing at which it heard the expert testimony of the lead customer support engineer at SST, Inc., described as a company that "sells a product called the Shotspotter to cities across the country," and the court subsequently denied the defendant's motion for reasons it explained in a 15-page order. ( Id . at pp. 774-778, 782, 851 N.W.2d 670.) The Nebraska Supreme Court, analyzing the trial court's decision under Nebraska's " Daubert / Schafersman jurisprudence," a standard similar to California's Kelly / Frye standard, concluded the trial court did not abuse its discretion in denying Hill's motion. ( Hill, at pp. 792-794, 851 N.W.2d 670.) It summarized Shotspotter as follows:"The ShotSpotter is an acoustic gunfire detection and location system of GPS-enabled microphones placed in various locations of a municipal area. SST has been in existence since 1995 and has been selling and maintaining ShotSpotter systems since 1996. In the summer of 2011, SST installed a ShotSpotter system in northeast Omaha.... [¶] [T]he ShotSpotter system in Omaha consisted of approximately 80 sensors, spaced roughly 400 to 500 meters apart. Each sensor has four GPS-enabled microphones. The digital signal processors of the sensors measure sound input to determine if the sound meets 28 different audio characteristics of ‘impulsive audio pulses,’ or a ‘bang, boom, or pop,’ and could thus be categorized as a possible gunshot. [¶] If the sound meets the preprogrammed criteria for a possible gunshot, the system transmits the information to a central location server, which uses triangulation to pinpoint the latitude and longitude of the sound and uses a process called ‘geolocation’ to place that location on a map. [¶] Incident review staff in California then quickly look at the audio waveform and listen to a recording of the event to discern if it is a false positive for a possible gunshot. Once the incident review staff rule out a false positive, they send an alert to the police dispatchers." ( Hill , supra , 288 Neb. at p. 775, 851 N.W.2d 670.)
Under Nebraska's Daubert / Schafersman jurisprudence, "the trial court acts as a gatekeeper to ensure the evidentiary relevance and reliability of an expert's opinion" to "ensure that the courtroom door remains closed to ‘ "junk science" ’ that might unduly influence the jury, while admitting reliable expert testimony that will assist the trier of fact." (Hill , supra , 288 Neb. at p. 792, and fns. 39 and 40, 851 N.W.2d 670, citing Daubert v. Merrell Dow Pharmaceuticals, Inc. (1993) 509 U.S. 579, 113 S.Ct. 2786, 125 L.Ed.2d 469 and Schafersman v. Agland Coop (2001) 262 Neb. 215, 631 N.W.2d 862.)
The Shotspotter expert "testified that the incident review staff are specially trained in recognizing the audio waveform characteristics of gunfire and in recognizing the sound of gunfire," and were required "to correctly identify 80 percent of 500 audioclips during performance testing." ( Hill , supra , 288 Neb. at p. 775, 851 N.W.2d 670.) Further, "the mathematical principles" behind the triangulation method used to determine location were "actually very old," and "[t]he practical application of it" dated back to World War I. ( Id . at pp. 775-776, 851 N.W.2d 670.) Shotspotter used a redundancy of sensors and required only three "to actually hear and participate in the incident." ( Id . at p. 776, 851 N.W.2d 670.) The expert further testified that the Shotspotter system was designed to make accurate detections if up to 20 percent of sensor capacity was lost, at which point the company dispatched repair technicians. ( Hill, supra, 288 Neb. at pp. 776-777, 851 N.W.2d 670.) Shotspotter's "official margin of error for the location of detected gunfire" was a 150-foot radius, but it "regularly achieve[d] accuracy of a radius of 10 or 20 feet or better." ( Id . at p. 776, 851 N.W.2d 670.) Shotspotter "guarantee[d] that it will give a correct location, within this margin of error, for 80 percent of detectible outdoor gunfire in the system area. Gunfire that is silenced or masked by other sounds is not considered detectible." ( Ibid . )
This summary indicates that Shotspotter's technology remains sufficiently novel to merit our courts’ review of it under Kelly / Frye to determine its scientific validity and reliability before admitting Shotspotter evidence to prove the facts of a particular shooting. And even assuming review of such evidence by another state's court could be considered for that purpose in California courts, there is no evidence that the technology used by the Oakland Police Department or the staff review methodology it or Shotspotter employed in Oakland in September 2018 were the same as those used in Omaha, Nebraska in 2012. For this reason, as well as the lack of any case law before or after Hill , in California or any other court, establishing the reliability of Shotspotter evidence, we hold that the trial court was required to review the Shotspotter evidence under Kelly / Frye when offered to prove the number of shots fired before admitting it. Therefore, the trial court erred by failing to do so.
See also United States v. Rickmon (7th Cir. 2020) 952 F.3d 876, in which the court discussed a motion to suppress evidence of a firearm seized at a traffic stop that resulted from a Shotspotter report of shots fired at a particular time and place. (Id . at pp. 879-880.) The district court had "received evidence that [Shotspotter] is not always accurate and that officers may not solely rely on it to locate gunfire." (Id . at p. 879, fn. 2.) However, the appellate court determined that the defendant's argument did not require it to "reach the reliability of Shotspotter," although "[i]n some future decision, we may have to determine Shotspotter's reliability where a single alert turns out to be the only articulable fact in the totality of the circumstances." (Ibid ., citing Hill , supra , 288 Neb. 767, 851 N.W.2d 670.)
Moreover, because there was no Kelly / Frye hearing, the prosecution failed to meet its burden of satisfying the three prongs of the Kelly / Frye reliability test. (See Lucas , supra , 60 Cal.4th at p. 244, 177 Cal.Rptr.3d 378, 333 P.3d 587 [outlining the three prongs].) That is, the prosecution presented no evidence that Shotspotter's technology was generally accepted as reliable in the pertinent scientific community. Officer Rosin was not offered as an expert and said nothing indicating he was anything more than a user of the technology. And the prosecution offered no proof that the Shotspotter data used by police in this case was the product of scientifically reliable technologies and procedures.
The People argue the trial court properly admitted the Shotspotter evidence for two reasons. First, Officer Rosin did not need to testify about how Shotspotter worked because "[h]is testimony did not portray a‘ "misleading aura of certainty" ’ " to the jury requiring a Kelly / Frye hearing. Second, the audio recording was admissible as a writing under Evidence Code section 250 because Officer Rosin testified it was "consistent" with his personal observations, citing People v. Dawkins (2014) 230 Cal.App.4th 991, 1003, 179 Cal.Rptr.3d 101 [deputy's testimony was sufficient to authenticate an automated recording of a 911 call made to his department because he had general knowledge of the automated system, and had searched for, found and downloaded the recording from the system].) These arguments are unpersuasive for multiple reasons, most importantly because they address authentication, which is not at issue in this appeal, and do not contend with whether Shotspotter's technology was scientifically valid and properly applied as required under Kelly / Frye . Therefore, the trial court erred by admitting the Shotspotter evidence without limitation, an error that was compounded by the prosecution's argument that the evidence proved seven shots were fired.
Evidence Code section 250 states, " ‘Writing’ means handwriting, typewriting, printing, photostating, photographing, photocopying, transmitting by electronic mail or facsimile, and every other means of recording upon any tangible thing, any form of communication or representation, including letters, words, pictures, sounds, or symbols, or combinations thereof, and any record thereby created, regardless of the manner in which the record has been stored."
Further, Officer Rosin did not testify that he had any personal knowledge regarding Shotspotter's generation of the recording, unlike the deputy in Dawkins . Moreover, Rosin's testimony that the recording was "consistent" with what he witnessed on the night of the incident did not establish the recording's reliability on the only significant issue—whether Hardy fired more than six shots—because Rosin recalled only that he heard "six or seven shots." (Italics added.) That the recording was "consistent" with this recollection may have been relevant to the recording's authentication, but it did not mean the recording was sufficiently reliable to merit admission for the purpose of determining that Hardy discharged seven shots and, therefore, must have fired a semi-automatic firearm and not a revolver.
2. The Court's Error Requires Reversal .
The court's error was prejudicial and requires that we reverse Hardy's conviction on count 5, for assault with a semi-automatic weapon.
Hardy argues the trial court's error implicates federal constitutional rights directly affecting the ascertainment of his guilt on that count, citing Chambers v. Mississippi (1973) 410 U.S. 284, 302-303, 93 S.Ct. 1038, 35 L.Ed.2d 297. The People argue against reversal under the state standard for evaluating prejudice, People v. Watson (1956) 46 Cal.2d 818, 836, 299 P.2d 243 ( Watson ), contending it is not reasonably probable that, but for any error, Hardy would have received a better outcome.
Our Supreme Court, referring to federal constitutional rights to due process, has recognized that "the admission of evidence in violation of state law may also violate due process, but only if the error rendered the defendant's trial fundamentally unfair." (People v. Merriman (2014) 60 Cal.4th 1, 70, 177 Cal.Rptr.3d 1, 332 P.3d 1187 ; accord, People v. Falsetta (1999) 21 Cal.4th 903, 913, 89 Cal.Rptr.2d 847, 986 P.2d 182 ["The admission of relevant evidence will not offend due process unless the evidence is so prejudicial as to render the defendant's trial fundamentally unfair"]; People v. Partida (2005) 37 Cal.4th 428, 439, 35 Cal.Rptr.3d 644, 122 P.3d 765 [quoting Falsetta ].) An appellate court has further explained, " ‘Only if there are no permissible inferences the jury may draw from the evidence can its admission violate due process. Even then, the evidence must "be of such quality as necessarily prevents a fair trial." [Citation.] Only under such circumstances can it be inferred that the jury must have used the evidence for an improper purpose.’ (Jammal v. Van de Kamp (9th Cir. 1991) 926 F.2d 918, 920.)" (People v. Hunt (2011) 196 Cal.App.4th 811, 817, 127 Cal.Rptr.3d 89.)
We conclude the error was prejudicial under any standard, including the Watson "reasonable probability" standard for state law error that the People argue we should apply. A "reasonable probability" "does not mean more likely than not, but merely a reasonable chance , more than an abstract possibility ." ( College Hospital Inc. v. Superior Court (1994) 8 Cal.4th 704, 715, 34 Cal.Rptr.2d 898, 882 P.2d 894.) It "does not mean ‘more likely than not,’ but merely ‘probability sufficient to undermine confidence in the outcome.’ " ( Ibid ., favorably quoting Strickland v. Washington (1984) 466 U.S. 668, 693-694, 697, 698, 104 S.Ct. 2052, 80 L.Ed.2d 674.) Therefore, reversal is necessary when it cannot be determined whether or not the error affected the result, as in such a case there "exists ... at least such an equal balance of reasonable probabilities" " ‘that it is reasonably probable that a result more favorable to the appealing party would have been reached in the absence of the error.’ " ( Watson , supra , 46 Cal.2d at pp. 837, 299 P.2d 243.) Such is the case here.
The Shotspotter evidence was the only unambiguous evidence that Hardy had fired seven shots and, therefore, must have used a semi-automatic firearm rather than a revolver, which could only fire up to six shots. Otherwise, the People presented a murky case for which there is at least an equal chance that a reasonable juror would or would not find Hardy culpable for assault with a semi-automatic firearm. No firearm associated with the bullet casings found at the scene was ever recovered; the main percipient witness to the shooting, Officer Rosin, testified only that Hardy had fired "six or seven shots" (italics added) from a weapon the officer did not see; the other percipient witness, Officer Coleman, testified that he heard "about six " shots (italics added); the surveillance video that captured Hardy as he fired did not show the weapon he used, had no audio, and revealed only two muzzle flashes; and only six bullet casings were found in the vicinity of where Rosin testified he saw Hardy fire.
The best indication that Hardy fired a semi-automatic firearm, other than the Shotspotter evidence, was the testimony of Officers Coleman and Airoso, based on their own experiences, that a semi-automatic firearm automatically ejects bullet casings as it is fired, coupled with the evidence that casings were recovered on the grassy and paved areas of the sidewalk. But this evidence was far from conclusive. First, only six casings were found. Second, Officer Coleman acknowledged that such bullet casings could be manually emptied out of a revolver. Third, the surveillance video shows that a few moments passed between the time Hardy appeared to fire something and the time he began walking down Olive behind his two associates. Fourth, Officer Rosin was not asked about and did not testify as to whether he had observed Hardy's actions during that time or saw bullet casings being ejected from the firearm. The part of Officer Rosin's testimony that is relevant to whether Hardy fired a semi-automatic or a revolver also raised as many questions as it provided answers. Officer Rosin acknowledged that he did not see the type of firearm Hardy used. He could only recall that he heard "six or seven" shots and, similarly, that a revolver could fire "five or six" shots. And he remembered seeing spent casings lying in the street on 90th Avenue, but according to the police evidence technician, none were found there.
Officer Coleman also testified that shell casings ejected from a semi-automatic pistol have ejector marks on them, but neither party contends his testimony, unaccompanied by any evidence that such marks appeared on the casings admitted into evidence, demonstrates that Hardy used a semi-automatic pistol.
The ambiguity resulting from the other evidence explains why the prosecutor placed the Shotspotter evidence front and center in his closing argument, playing the audio recording to the jury at the outset and referring to the seven percussive sounds that could be heard on it repeatedly in his argument. The Shotspotter evidence, particularly the audio recording, was almost certainly decisive, and what verdict the jury would have reached on count 5 without it is entirely unclear. This lack of clarity undermines our confidence in the verdict on count 5 and requires us to reverse under any prejudice standard.
See footnote *, ante .
DISPOSITION
Hardy's conviction on count 5, for assault with a semi-automatic firearm in violation of section 245, subdivision (b), is reversed. The judgment is otherwise affirmed. The matter is remanded to the trial court for further proceedings consistent with this opinion.
Following People v. Leahy (1994) 8 Cal.4th 587, we direct the trial court to conduct a Kelly/Frye hearing regarding count 5 in accordance with our opinion. If, at the conclusion of the hearing, the trial court concludes there is sufficient basis to properly admit the Shotspotter evidence previously presented, the court should reinstate the judgment. If the trial court determines the evidence is insufficient to properly admit the Shotspotter evidence presented, then the court may order a new trial, if the People so elect. If the judgment is reinstated, or a new trial ordered, appellate review will be available to the parties regarding the trial court's ruling, limited to any new issues not previously resolved in this opinion. (See Leahy , at pp. 612-613.) Also, should the trial court rule there is insufficient evidence to properly admit the Shotspotter evidence presented, nothing in this opinion is intended to preclude the People from pursuing entry of a judgment of conviction on count 5 for a lesser included offense, including on the accompanying enhancement, instead of retrying that count, under People v. Kelly (1992) 1 Cal.4th 495, 528, if supported by law and the record in this case.
We concur.
