THE PEOPLE DID NOT DEMONSTRATE THAT THE ANALYST WHO TESTIFIED ABOUT THE GENERATION OF THE DNA PROFILE HAD FIRST-HAND KNOWLEDGE OF THE PROCEDURE USED OR INDEPENDENTLY ANALYZED THE RAW DATA; NEW TRIAL ORDERED (SECOND DEPT).

The Second Department, reversing defendant’s conviction, determined the defendant was deprived of the opportunity to cross-examine a witness who had first-hand knowledge of the generation of the DNA profile:

When confronted with testimonial DNA evidence at trial, a defendant is entitled to cross-examine “an analyst who witnessed, performed or supervised the generation of defendant’s DNA profile, or who used his or her independent analysis on the raw data” … . As the defendant contends, the People failed to establish that the analyst who testified in this case performed such a role in the testing or analysis of the testimonial DNA evidence introduced against him at trial … . Since the error was not harmless, the defendant is entitled to a new trial … . People v Butler, 2020 NY Slip Op 02676, Second Dept 5-6-20
