REQUEST FOR A FRYE HEARING CONCERNING A COMPUTER PROGRAM (TRUEALLELE) THAT PURPORTS TO IDENTIFY DNA CONTAINED IN A MIXTURE THAT COULD NOT OTHERWISE BE TIED TO THE DEFENDANT PROPERLY DENIED BASED ON THE RESULTS OF A HEARING ON THE SAME ISSUE IN ANOTHER CASE, EVEN THOUGH THAT CASE IS ON APPEAL, DEFENSE REQUEST FOR THE ORIGINAL CODE FOR THE PROGRAM, MADE FOR THE FIRST TIME DURING CROSS-EXAMINATION OF THE PEOPLE’S EXPERT, PROPERLY DENIED (THIRD DEPT).

The Third Department determined Supreme Court properly denied a DNA-related Frye hearing based on a Frye hearing held in another case, even though that case is on appeal. The hearing was requested concerning a computer program (TrueAllele) which calculates the probability a defendant’s DNA is in a mixture that could not otherwise be definitively tied to the defendant. The original code for the computer program, called the source code, could have been requested by the defendant for a pre-trial analysis by a defense expert. The defense never requested the source code but attempted to have the TrueAllele expert provide the source code during cross-examination. The argument that cross-examination was impeded because the source code was not made available to the defense at trial was rejected. Only an expert could analyze it and there had been no timely request for it by the defense:

…DNA analysis did not definitively tie defendant to the genetic material recovered from the pistol. The People accordingly sought to present proof of a re-analysis conducted with the TrueAllele Casework System (hereinafter TrueAllele), a computer program that subjects a DNA mixture to statistical modeling techniques to infer what DNA profiles contributed to the mixture and calculate the probability that DNA from a known individual contributed to it. Defendant argued that the TrueAllele evidence should be precluded or that the general acceptance of the technique in the scientific community should be assessed via a Frye hearing. Supreme Court denied the application due to the fact that an extensive Frye hearing had been conducted on the issue in another criminal case in the same county and that a determination, issued weeks before the trial in this matter, was rendered finding that the procedure was not novel and was generally accepted by the relevant scientific community … . People v Fields, 2018 NY Slip Op 02503, Third Dept 4-12-18
