Opinion

SULLIVAN, C.J.

A jury found the defendant, Jose Colon, guilty of one count of murder in violation of General Statutes § 53a-54a (a) and one count of conspiracy to commit murder in violation of General Statutes §§ 53a-48 and 53a-54a (a). The trial court sentenced him to a term of imprisonment of fifty-five years on the murder conviction and twenty years on the conspiracy conviction, to run concurrently, for a total effective sentence of fifty-five years. The defendant appealed from that judgment to the Appellate Court, claiming that the trial court improperly denied his motion for judgment of acquittal on the conspiracy conviction after his sole alleged coconspirator was acquitted of conspiracy in a separate, subsequent trial. The defendant argued that this outcome was in direct conflict with State v. Grullon, 212 Conn. 195, 562 A.2d 481 (1989), and State v. Robinson, 213 Conn. 243, 567 A.2d 1173 (1989), both of which held that § 53a-48 is strictly a bilateral conspiracy statute. We transferred the appeal to this court pursuant to Practice Book § 65-1. We now conclude that § 53a-48 (a) can be interpreted unilaterally in those cases in which alleged coconspirators are tried separately based on independent evidence of the crime of conspiracy. Accordingly, the defendant's conviction is affirmed.

The jury reasonably could have found the following facts. Sergeant Michael Fischer of the Waterbury police department testified that on April 22, 1996, the Waterbury police received an anonymous telephone call alerting them to a possible homicide at an abandoned building on Ridgewood Street in Waterbury. When the police arrived, they discovered the bloody body of the victim. The victim had been stabbed several times in the head, neck, arms and torso, and also appeared to have been beaten about the head. A metal pipe and a small buck knife covered in blood and hair were discovered at the crime scene. An autopsy conducted by Edward T. McDonough, the deputy chief medical examiner, revealed that the victim had approximately "125 . . . sharp force injuries . . . he had cuts and stabs over the head, the face, the front of the trunk, the back, and the arms and both legs." The victim also had on his arms, hands and wrists several cuts that were consistent with defensive injuries, as though he had been attempting to protect himself from the blows. The autopsy revealed that the wounds had been inflicted by the buck knife and the metal pipe discovered at the scene, and that another, much larger, weapon also had been used in the attack. Michael Silva, a forensic crime scene technician, described the victim's wounds as appearing to have been inflicted by a knife that was "large . . . approximately eight inches long with a fat blade with a brass type of guard to it." Silva also testified that the "cast off" patterns of blood at the crime scene illustrated that the victim had suffered a "severe attack," that the "assailant was swinging very, very violently at the victim," and that the wall behind the victim showed signs of "actual misses . . . [that occurred when] the assailant swung the weapon . . . against the wall. . . ." He also testified that the hair pattern on the wall behind the victim indicated that he was struck several times in the head. It was the opinion of McDonough and Silva that, as a result of the combined sharp force injuries, the victim bled to death over a period of time.

Lieutenant Michael Ricci of the Waterbury police department testified that on April 23, 1996, the day after the body was discovered, police officers began questioning local residents about the homicide. After being shown a police photograph, the victim's father identified the victim as his son, Hector Nieves. Once the victim was identified, Ricci and several other officers interviewed area residents in an effort to identify the individual who had made the anonymous call to the Waterbury police. Ricci interviewed Kevin Soto and his girlfriend, Edith Santos, who appeared to have been acquainted with the victim. Ricci requested that the couple come down to the police station the next day to listen to a recording of the unidentified 911 caller. While Soto was at the station, Ricci realized that it was his voice on the 911 tape. Soto then admitted making the call and, after being issued a Miranda warning, disclosed his role in the crime and implicated the defendant as the principal actor. See State v. Soto, 59 Conn. App. 500, 502-503, 757 A.2d 1156, cert. denied, 254 Conn. 950, 762 A.2d 906 (2000). Ricci testified that, after Soto's disclosure, several officers were dispatched to Kennedy high school in Waterbury to bring the defendant in for questioning. Shortly after his arrival, and after being issued a Miranda warning, the defendant admitted to the officers his participation in the murder.

Ricci testified that, after taking a written statement from the defendant, police officers spoke to Soto a second time about the homicide and also interviewed Santos. Santos gave the police two different statements regarding the events of that day, one before and one after the defendant was placed under arrest. Initially, Santos did not implicate the defendant in the murder. She testified at trial that, when she gave her first statement to the police, she had been afraid that the defendant was still out on the street. Once she knew the defendant was in custody, however, she disclosed to police everything she knew about the murder. Thus, during her second interview with the police, Santos disclosed that she was with Soto at his mother's residence on the day of the murder. She observed Soto leave the residence with the victim and then return about one half hour later. Santos told the police that, when Soto returned to his mother's home after spending time with the defendant, he was acting strangely. When she asked what was wrong, Soto revealed to her that he and the defendant had stabbed the victim. Soto then told Santos that they had to go to her apartment because the defendant was there. When Santos arrived at her apartment and saw the defendant, she could see that he was "full of blood from head to toe." The defendant took a large "sword" out of his sleeve and showed it to her. It also was covered in blood. Santos got the defendant a garbage bag for his bloody clothes, while he showered and changed into clean clothes. Santos testified that, after speaking with Soto, she asked the defendant if the victim was dead and he responded affirmatively. Santos then testified that she, Soto and the defendant left her apartment, and the defendant deposited the bag of bloody clothes behind an abandoned building. When Soto and Santos parted ways with the defendant, they decided to call 911.

Two additional witnesses provided information on the "large sword" Santos described in her statement to the police. Ivan Pagan testified that, on the day of the murder, the defendant came to his house and took a "Pakistani sword" that he was holding for a relative. Ivan Pagan testified that the defendant returned approximately one hour later, in different clothes, and gave the sword back to him with a dent in the tip, covered in fresh blood and hair. The defendant told Ivan Pagan that "he [had] killed [Hector from] up the street." Ivan Pagan took the sword, cleaned it with alcohol and a rag, wrapped it in tape and placed it in his closet. Later that evening, he hid the sword "on the roof by the side of [his] house" covered in branches. Ivan Pagan testified that his fear of the defendant prompted him to take the sword and hide it for him as instructed. Danny Pagan, Ivan Pagan's brother, testified that he saw the defendant speak to Ivan Pagan on April 22, 1996. He testified that he observed the defendant meet Soto up the street, and then place the "Pakistani knife" in his pants. When Danny Pagan asked the defendant where he was going, the defendant answered that he was going up the block "on a mission" with Soto. Later that day, Danny Pagan saw the defendant return to their neighborhood and speak to his brother. Ivan Pagan later told Danny Pagan that the defendant revealed to him that he had killed the victim. The next day, Danny Pagan saw the defendant speak to the police and deny that he was "Cujo," a name the police had learned the defendant was called on the street. After speaking with the police, the defendant approached Danny Pagan and told him that he and Soto had killed somebody with the sword, and he instructed Danny Pagan to move it from its initial hiding place. Danny Pagan testified that after his conversation with the defendant, he moved the sword from the roof where his brother had hidden it, wrapped it in a black plastic bag and placed it in a nearby abandoned garage.

Mark Deal, a Waterbury police officer, took a statement from the defendant that was read into the record at trial. In his statement, the defendant stated that he met Soto on Hillside Avenue in Waterbury on April 22, 1996. Soto, a member of the Latin Kings gang, told the defendant that the victim had "disrespected the [Latin Kings] nation" and that they had to "work him over." The defendant stated that he and Soto approached the victim and asked him if he wanted to smoke a "blunt," or a marijuana cigarette, in an abandoned building on Ridgewood Street. The defendant walked into the building before Soto and the victim, but turned around when he heard the victim say, "Oh Kevin, why did you do that?" The defendant stated that when he turned around, the victim was holding his throat. When the victim took his hand away, the defendant stated that he saw a lot of blood coming from the victim's throat. Soto had pushed the victim to the floor and shut the door. The defendant then stated that Soto passed him the knife and he stabbed the victim in the chest. When the victim resisted the attack, the defendant punched him and swung at him with the knife, while Soto beat him with a long metal bar. The defendant stated that he remembered stabbing the victim approximately five times before Soto said "let's get out of here." The defendant stated that the victim was still moving when they left him. After the defendant and Soto left the scene, they went to the home of Santos where they cleaned the victim's blood off themselves and changed their clothes. In his statement, the defendant identified Soto as the other participant in the killing and described the murder weapon and the clothing he wore the night of the murder.

The jury began deliberations on October 26, 1998. On October 27, 1998, the jury returned a verdict of guilty on all charges. At the sentencing phase of the trial, the defendant filed a postverdict motion for judgment of acquittal on the conspiracy charges because his sole alleged coconspirator had been acquitted of conspiracy in a separate trial after the defendant's conviction but prior to his sentencing. See State v. Soto, supra, 59 Conn. App. 502 n. 2. The defendant relied upon State v. Grullon, supra, 212 Conn. 195, and State v. Robinson, supra, 213 Conn. 243, for his argument that, as a matter of law, a defendant cannot be guilty of conspiracy to commit a crime when his sole alleged coconspirator has been acquitted of conspiracy charges stemming from the same crime. The defendant argued that, because his sole alleged coconspirator, Soto, was tried on the same charges, based on identical underlying facts, and acquitted by a jury of the charge of conspiracy to commit murder prior to the defendant's sentencing, he also must be acquitted of the conspiracy charges. The defendant asserted that, because Connecticut's conspiracy statute requires bilateral agreement, the acquittal of one conspirator necessarily precludes the conviction of the sole alleged coconspirator. The trial court disagreed.

Finding Robinson to be factually distinguishable from the present case, the trial court made the following finding: "The court feels the factual pattern here is unlike . . . Robinson. I think that the fact pattern here triggers the case law that allow[s] inconsistent verdicts at separate trials. I don't believe it is the policy of the state or the law of the state to undo serious convictions based upon what another jury does in subsequent cases on somewhat different evidence that was presented to that jury." The trial court went on to state: "In fact, the Court's recollection . . . [is] that when the two met to gather the sword to move on . . . the evidence against [the defendant] said that they were `going on a mission,' which the jury in [this] case could have interpreted to be a conspiracy. That evidence, my recollection [is], was absent in the case of Mr. Soto, so that two juries, one subsequent to the other, [heard] different evidence, allow[ing] inconsistent verdicts." Accordingly, the trial court denied the defendant's motion for judgment of acquittal. We agree with the trial court's reasoning.

General Statutes § 53a-48 (a) provides that "[a] person is guilty of conspiracy when, with intent that conduct constituting a crime be performed, he agrees with one or more persons to engage in or cause the performance of such conduct, and any one of them commits an overt act in pursuance of such conspiracy. . . ." Generally, "[i]n construing a statute, [o]ur fundamental objective is to ascertain and give effect to the apparent intent of the legislature. . . . In seeking to discern that intent, we look to the words of the statute itself, to the legislative history and circumstances surrounding its enactment, to the legislative policy it was designed to implement, and to its relationship to existing legislation and common law principles governing the same general subject matter." (Internal quotation marks omitted.) State v. Parra, 251 Conn. 617, 622, 741 A.2d 902 (1999). In Grullon and Robinson, we determined that the language of § 53a-48 (a) supported a bilateral interpretation of our conspiracy laws. State v. Grullon, supra, 212 Conn. 195; State v. Robinson, supra, 213 Conn. 243. "Our examination of the definition of the crime of conspiracy in § 53a-48 convince[d] us that the legislature [had] determined that conspiracy require[d] a showing that two or more coconspirators intended to engage in or cause conduct that constitute[d] a crime." (Internal quotation marks omitted.) State v. Robinson, supra, 250.

In arguing that he could not be convicted of conspiracy once Soto, his sole alleged coconspirator, was acquitted, the defendant relied upon State v. Grullon, supra, 212 Conn. 195, and State v. Robinson, supra, 213 Conn. 243. We now conclude, however, that Grullon and Robinson are factually distinguishable from one another and, therefore, that the rule in Grullon should not have governed our decision in Robinson. In Grullon, we concluded that a defendant could not be guilty of conspiracy pursuant to § 53a-48 without proof beyond a reasonable doubt that he conspired with another individual who was not a police informant or agent because the statute requires that there be an agreement between coconspirators. State v. Grullon, supra, 198-99. In Grullon, the defendant had conspired with a police agent to deliver a shipment of narcotics. The agent did not have the actual intent to commit the crime. Id., 203-204. In Robinson, however, the defendant and his coconspirator both were charged with conspiracy to commit murder and both went to trial in different proceedings. State v. Robinson, supra, 250. The defendant was convicted on the conspiracy charge, but his coconspirator was acquitted. Id. Relying on the Grullon requirement for bilateral conspiracy, we concluded that the acquittal, at a separate trial, of the defendant's alleged coconspirator foreclosed prosecution of the defendant for conspiracy because the culpability of the coconspirator was "an essential element of the defendant's offense." Id., 253.

On the basis of their significant factual differences, however, we now conclude that our reliance on Grullon in deciding Robinson was improper. "The earlier determination in . . . Grullon . . . that General Statutes § 53a-48 is a `bilateral' conspiracy statute does not offer any real insight in addressing the present issue. Nor does the line of cases holding that the acquittal of one conspirator forecloses the conviction of other conspirators found guilty in the same trial. This rule, while making obvious sense in the context of a single trial for all of the reasons stated in the majority opinion, has been rejected by a number of jurisdictions where, as here, the acquittal occurs in a separate trial. See United States v. Irvin, 787 F.2d 1506, 1512-14 (11th Cir. 1986); United States v. Roark, 753 F.2d 991, 995-96 (11th Cir.), reh. denied, 761 F.2d 698 (11th Cir. 1985); United States v. Espinosa-Cerpa, 630 F.2d 328, 330-32 (5th Cir. 1980); Gardner v. State, 286 Md. 520, 524-29, 408 A.2d 1317 (1979); Commonwealth v. Brown, 473 Pa. 458, 463-67, 375 A.2d 331 (1977)." State v. Robinson, supra, 213 Conn. 262-63 ( Covello, J., dissenting).

In Grullon, the police agent never intended to commit the underlying crime and, therefore, there was no agreement as required by the statute. State v. Grullon, supra, 212 Conn. 203. In Robinson, however, the coconspirators were both charged with the underlying, substantive crime of conspiracy, and both coconspirators were charged with having the underlying necessary intent to enter into the conspiracy. State v. Robinson, supra, 213 Conn. 250. Thus, although we recognize that "[t]he doctrine of stare decisis counsels that a court should not overrule its earlier decisions unless the most cogent reasons and inescapable logic require it"; (internal quotation marks omitted) State v. Murray, 254 Conn. 472, 499, 757 A.2d 578 (2000) ( McDonald, C.J., dissenting); it is evident that the facts of these two cases warrant different results and Robinson should be overruled. We noted in Grullon that "[a]llowing a government agent to form a conspiracy with only one other party would create the potential for law enforcement officers to manufacture conspiracies when none would exist absent the government's presence." (Internal quotation marks omitted.) State v. Grullon, supra, 203. We reaffirm that principle and decline to overrule Grullon. For the following reasons, however, we conclude that the rule in Robinson, although "once believed sound, needs modification to serve justice better. . . . [This] court, when once convinced that it is in error, is not compelled to follow precedent." (Internal quotation marks omitted.) George v. Ericson, 250 Conn. 312, 318, 736 A.2d 889 (1999). We now conclude, therefore, that the conviction of a conspirator may be upheld despite the acquittal of his sole alleged coconspirator in a separate trial where there is sufficient evidence to prove, beyond a reasonable doubt, that the defendant was guilty of conspiracy.

In Robinson, we held that, "as a matter of law, the conspiracy charge against the defendant was barred after the acquittal of the sole alleged coconspirator." State v. Robinson, supra, 213 Conn. 253. We enumerated therein those jurisdictions that had taken a similar position. Id., 253 n. 8. We also recognized, however, that authorities are split over whether criminal liability under conspiracy laws should be extended to situations where a defendant's coconspirator has been acquitted in a prior trial before a different jury. Id., 251-52, citing 19 A.L.R. 4th 192 and cases cited therein. The courts that find liability in such cases have reasoned that "an acquittal is not tantamount to a determination of innocence and that the proof may differ from one trial to another. Central to that reasoning of these courts is their contention that consistent verdicts, even as to conspiracy convictions, are not required at separate trials." Id., 252. We now consider the rationale of those jurisdictions persuasive.

When coconspirators are tried separately, the acquittal of one on charges of conspiracy should not dictate the acquittal of the other simply because the state in one case has failed to prove an element necessary to a conspiracy charge. See United States v. Espinosa-Cerpa, supra, 630 F.2d 332 (jury's acquittal of some coconspirators should not be taken to negate fact of possible criminal complicity with any remaining alleged coconspirators); People v. Berkowitz, 50 N.Y.2d 333, 346, 406 N.E.2d 783, 428 N.Y.S.2d 927 (1980) (principles of collateral estoppel do not bar prosecution of one conspirator after acquittal of sole coconspirator in criminal trial). The acquittal of a codefendant in a separate trial "could . . . [result] from a multiplicity of factors completely unrelated to the actual existence of a conspiracy"; United States v. Strother, 458 F.2d 424, 426 (5th Cir.), cert. denied, 409 U.S. 1011, 93 S.Ct. 456, 34 L.Ed.2d 305 (1972); for example, certain evidentiary issues that might render evidence inadmissible in one trial but not in another. See Rosencrans v. United States, 378 F.2d 561, 567 (5th Cir. 1967); Marquiz v. People, 726 P.2d 1105, 1107 (Colo. 1986). In separate trials, "[t]he evidence presented to the juries and the manner in which that evidence is presented may be significantly different and certainly will never be identical." Marquiz v. People, supra, 1107. As a result, "[d]ifferent juries may rationally come to different conclusions, especially when differing evidence is presented." United States v. Roark, supra, 753 F.2d 995.

"An . . . unsuccessful prosecution of an alleged coconspirator in a separate trial means nothing more than that on a given date the prosecution failed to meet its burden of proving the defendant guilty beyond a reasonable doubt of all of the elements constituting conspiracy. It certainly does not mean . . . that a conspiracy did not occur. It has long been recognized that criminal juries in the United States are free to render not guilty verdicts resulting from compromise, confusion, mistake, leniency or other legally and logically irrelevant factors." (Internal quotation marks omitted.) State v. Robinson, supra, 213 Conn. 263 ( Covello, J., dissenting), citing Dunn v. United States, 284 U.S. 390, 393-94, 52 S.Ct. 189, 76 L.Ed. 356 (1932). "Consequently, an acquittal is not to be taken as the equivalent of a finding of the fact of innocence; nor does it necessarily even reflect a failure of proof on the part of the prosecution." (Internal quotation marks omitted.) State v. Robinson, supra, 263 ( Covello, J., dissenting), quoting United States v. Espinosa-Cerpa, supra, 630 F.2d 332. We reject the rule established in Robinson that one conspirator cannot be convicted when his sole alleged coconspirator is acquitted in a separate proceeding. We recognize that "[w]hile symmetry of results may be intellectually satisfying, it is not required." (Internal quotation marks omitted.) United States v. Roark, supra, 753 F.2d 996, quoting Standefer v. United States, 447 U.S. 10, 25, 100 S.Ct. 1999, 64 L.Ed.2d 689 (1980).

The defendant in this case was tried and convicted by a jury that was presented with a specific body of facts, some of which were not presented in Soto's trial. For example, the jury in this case heard testimony of the "mission" upon which the defendant and his coconspirator embarked when they conspired to murder the victim. That evidence was inadmissible at the trial of the defendant's coconspirator, which may have been a factor in his acquittal on the conspiracy charge. The acquittal of the defendant's coconspirator did not nullify the defendant's conviction of the same charge, where the two defendants were tried separately, and their respective juries were presented with separate, independent evidence of their agreement to commit the crime in question. Accordingly, we conclude that the trial court properly concluded that the defendant's conviction should stand despite Soto's acquittal and, therefore, that it properly denied the defendant's motion for judgment of acquittal.
