Improper Evidence of Uncharged Offenses, a Police Officer’s Vouching for the Reliability and Credibility of the People’s Central Witness, and the Court’s Failure to Give Limiting Instructions to the Jurors after Sustaining Objections to Improper Testimony Deprived Defendant of a Fair Trial

The Third Department reversed defendant’s conviction based upon several errors including the improper presentation of evidence of uncharged crimes attributed to the defendant and a police officer’s vouching for the reliability and credibility of the confidential informant (CI), upon whose testimony the People’s case depended. The jury heard evidence of defendant’s participation in a drug offense identical to that for which he was on trial. Even though objection to the testimony was sustained and the testimony struck, no limiting instructions were given to the jury. Evidence of defendant’s sitting at a table on which were large amounts of heroin and crack cocaine was also improperly presented. Objection to that testimony was overruled. With respect to the police officer’s vouching for the credibility and reliability of the CI, the defense objection to that testimony was sustained, but no curative instructions were given to the jury:

At trial … the CI testified that defendant was not only present during [a] controlled purchase of crack cocaine, but that he had also participated in the transaction by providing the actual drugs. County Court denied defendant’s prompt motion for a mistrial, but otherwise sustained his objection and struck this portion of the CI’s testimony, without further limiting instructions to the jury. In our view, this revelation was highly prejudicial, as it related to a recent uncharged crime that was nearly identical to the sale for which defendant was on trial … . Shortly thereafter, the CI recounted that, upon entering the apartment on October 9, 2012, he had observed defendant sitting at a table “with large amounts of heroin and crack cocaine in front of him.” Although no reference to “heroin” was included in the People’s Molineux proffer, or otherwise previously disclosed, the court overruled defendant’s objection, permitting further testimony from the CI about the presence of heroin. Because defendant was not charged with possession or sale of heroin, it cannot be said that this evidence was directly related to or in any way necessary to explain his alleged possession and sale of crack cocaine such that it was inextricably interwoven into the CI’s narrative … . Significantly, the court did not attempt to cure the prejudice arising from the CI’s improper testimony by issuing an instruction either at the time of defendant’s objection or during the jury charge … . * * *

Further prejudice resulted from the People’s redirect examination of [officer] Gillis, who stated that the CI was “very reliable and very trustworthy.” After County Court overruled defendant’s objection, and characterized the testimony as “opinion,” Gillis elaborated that the CI had “never given [him a] reason to not believe anything that [the CI] is telling [him].” Allowing Gillis to vouch for the CI’s credibility was clearly improper … . The effect was compounded by the People’s summation, wherein the prosecutor surmised that law enforcement had used the CI for several years because of his reliability … . While we recognize that County Court sustained defendant’s objection, no curative instruction was issued, and we remain concerned that the prosecutor’s remark amplified the effect of Gillis’ improper vouching … .
