Ordered that the judgment is affirmed.
A juror may be discharged if the juror is grossly unqualified to serve in the case or has engaged in misconduct of a substantial nature (CPL 270.35). The trial court is in the best position to assess the partiality of an allegedly biased juror (see, People v. Rodriguez, 71 N.Y.2d 214). During the lunch recess, shortly after the People's first witness left the witness stand, the witness asked a juror: "how did I do," to which the juror replied: "fine". The court questioned the witness and the juror regarding the exchange and the juror stated that his ability to be impartial would not be affected. Further, the juror had not communicated the conversation to other jurors. Under the circumstances, the alleged misconduct was not of such a substantial nature that the court was required to discharge the juror (see, People v. Buford, 69 N.Y.2d 290, 299).
Moreover, it was reasonable for the court to charge the jury regarding reckless endangerment in connection with the theory of "acting in concert". Penal Law § 20.00 imposes accessorial liability when a person intentionally aids another person to engage in conduct which constitutes an offense, while himself acting with the mental culpability required for the commission of that offense (see, People v. Flayhart, 72 N.Y.2d 737, 741). Penal Law § 120.25 defines the requisite mental culpability for the crime of reckless endangerment in the first degree as conduct which creates a grave risk of death to another person (see, People v. Robinson, 43 A.D.2d 963). The evidence in the present case indicated that the defendant provided the codefendant with a loaded semi-automatic weapon when the codefendant asked for the weapon in a situation where two groups of men were arguing and there were many innocent people in the immediate vicinity. Further, the defendant testified that he knew people might be hurt if the codefendant shot the loaded gun. Thus, the defendant had the requisite mental culpability (see, People v. Graves, 131 A.D.2d 506, 508).
The defendant's remaining contentions are either unpreserved for appellate review (CPL 470.05; see, People v. Udzinski, 146 A.D.2d 245), or without merit. Mangano, P.J., Miller, Thompson and Joy, JJ., concur.
