Opinion

OPINION OF THE COURT

Marcy L. Kahn, J.

Defendants Aubin Debraux and Davone Merritt, by individual motions made in two separate indictments, have sought to preclude the People from introducing at their trials expert testimony as to any results derived from the use of the forensic statistical tool (FST), a mathematical computer software program developed and used by the Forensic Biology Unit of the New York City Office of the Chief Medical Examiner (OCME) to calculate a likelihood ratio that a specific individu[249]*249al’s deoxyribonucleic acid (DNA) is part of a mixture of DNA found on crime scene evidence. In the alternative, the defendants each seek hearings pursuant to Frye v United States (293 F 1013 [DC Cir 1923]). Because both of these motions raise identical legal issues and seek the same alternative forms of relief (among the others sought by the People and defendant Debraux, as discussed infra), and because the respective parties are represented in each case by the Office of the New York County District Attorney and the Legal Aid Society, this court has consolidated both cases solely for purposes of this decision and order.

I. Factual Background of the Cases

A. People v Debraux, Indictment Number 1653/2015

Defendant Debraux stands charged with one count of criminal possession of a weapon in the second degree (Penal Law § 265.03 [1] [b]) and one count of criminal possession of a weapon in the third degree (Penal Law § 265.02 [1]). By motion dated May 28, 2015 (affirmation of Robert Cannata, Esq., dated May 28, 2015, in support of order), the People moved for an order pursuant to CPL 240.40 (2) (b) (v) compelling defendant Debraux to provide a buccal swab for purposes of DNA testing by the OCME and comparison with a DNA sample derived from the swabbing of a semiautomatic handgun found in his hotel room after his departure. Testing of the sample conducted by the OCME revealed that the sample contained a mixture of DNA specimens from multiple contributors and that, although individual profiles could not be created, the results were found suitable for comparison with a DNA sample from an individual suspect.

B. People v Merritt, Indictment Number 3227/2014

Defendant Merritt stands charged with one count of attempted murder in the second degree (Penal Law §§ 110.00, 125.25 [1]), one count of attempted assault in the first degree (Penal Law §§ 110.00, 120.10 [1]), one count of assault in the second degree (Penal Law § 120.05 [2]), two counts of criminal possession of a weapon in the second degree (Penal Law § 265.03 [1] [b]; [3]) and one count of criminal possession of a weapon in the third degree (Penal Law § 265.02 [3]). These charges arose from a shooting incident that took place outside a juice bar located at the intersection of Seventh Avenue and West 123rd Street in Manhattan, where police subsequently recovered a firearm which defendant Merritt had allegedly used in the incident and then discarded.

[250]*250A swab taken from the back strap, side grips and front strap of the gun yielded a mixture of DNA from at least two contributors (People v Merritt, indictment No. 3227/2014, affirmation of Bejal J. Shah, Esq. and Allison Lewis, Esq., dated July 1, 2015, in support of motion to preclude expert testimony or for a Frye hearing [defendant Merritt’s motion], exhibit A [laboratory report, OCME, Sept. 17, 2014] at 2). Upon testing, the OCME was able to determine a 14-loci DNA profile of a major male contributor, to whom the OCME referred as “Male Donor A” (id.). A second swab taken from the trigger and trigger guard of the gun also yielded a DNA mixture, but the DNA profiles of its multiple individual contributors could not be determined (id.). The results of the testing of both swabs were found to be suitable for comparison, however (id.).

Sometime prior to February 27, 2015, a DNA sample taken from a cigarette butt smoked by defendant while he was at the police precinct was compared to that of Male Donor A (defendant Merritt’s motion, exhibit B [laboratory report, OCME, Feb. 27, 2015] at 2). The OCME determined that defendant Merritt was likely to be the major male contributor to the DNA mixture from which the profile of Male Donor A was developed and that the DNA profile of Male Donor A could be found in no more than one in greater than 6.8 trillion people (id. at 1).

From the DNA mixture taken from the trigger and trigger guard of the gun, using FST analysis, the OCME determined that it was 13.6 billion times more probable that that sample originated from defendant Merritt and two other, unknown, unrelated persons than from three unknown, unrelated persons (id. at 2). Accordingly, the OCME concluded that the test results provided “very strong support” for the conclusion that defendant Merritt and two other unknown persons contributed to that DNA mixture (id.).

C. Consolidated Motions to Preclude Expert Testimony or Alternatively for a Frye Hearing

By cross motion filed June 30, 2015 (People v Debraux, indictment No. 1653/2015, affirmation of Beth Unger, Esq., filed June 30, 2015, in opposition to motion to compel DNA), and by motion filed July 1, 2015 (defendant Merritt’s motion), defendants Debraux and Merritt, respectively, challenged the OCME’s use of the FST. Specifically, while conceding that the use of likeli[251]*251hood ratios, Bayesian mathematics1 and accounting for stochastic effects,2 which are central to the FST, are all generally accepted techniques in the forensic scientific community for evaluating the probability that an individual’s DNA is present in a sample of multiple contributors, defendants here contend that the manner in which the FST accounts for stochastic effects is not generally accepted as reliable by that community, requiring either the total preclusion of any expert testimony based upon the FST from their trials, or the holding of Frye hearings at which the prosecution would be required to demonstrate the reliability of the approach utilized in the FST to account for stochastic effects. In addition, defendant Merritt asserts that a pretrial hearing on the admissibility of the FST results in his case is needed because the probative value of the FST results as evidence is substantially outweighed by their prejudicial and misleading effect upon the jury.

In their responses to both motions (People v Debraux, indictment No. 1653/2015, affirmation of Melissa Mourges, Esq., dated July 15, 2015, in reply to defendant’s motion opposing buccal swab and requesting protective order; People v Merritt, indictment No. 3227/2014, affirmation of Melissa Mourges, Esq., filed Aug. 19, 2015, in reply to defendant’s motion for Frye hearing [People’s reply]), the People maintained that the FST meets the standard of general acceptance in the forensic scientific community as reliable in all respects and that a Frye hearing is unnecessary.3

D. Related Issues in People v Debraux

Defendant Debraux also opposed the taking of the buccal swab sample. Alternatively, he argued that the People’s motion [252]*252for buccal swab testing should be held in abeyance pending a Mapp hearing (Mapp v Ohio, 367 US 643 [1961]), and cross-moved for a protective order.
