Opinion
June 15, 1999.
Appeal from the Supreme Court, New York County (Jerome Hornblass, J.).
The court properly received background testimony regarding the workings of street-level drug selling operations from an officer whose testimony demonstrated that he had sufficient experience to qualify as an expert on that subject, notwithstanding that the court did not formally declare him to be an expert witness ( People v. Lacend, 216 A.D.2d 112, 113, lv denied 87 N.Y.2d 923). All of defendant's remaining challenges to the expert testimony are unpreserved ( People v. Tevaha, 84 N.Y.2d 879), and we decline to review them in the interest of justice. Were we to review these claims, we would find that the brief, limited, non-prejudicial testimony was necessary to explain the accessorial liability of the codefendant at this joint trial, and was also relevant to defendant's own guilt, especially with regard to his connection to a quantity of drugs not found on his person ( see, People v. Kelsey, 194 A.D.2d 248, 252-253).
Defendant's contention that the indictment was duplicitous is unpreserved, and we decline to review it in the interest of justice. Were we to review this claim, we would reject it.
