OPINION OF THE COURT
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
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.
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
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.
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
By written order dated August 5, 2015, this court granted the People’s motion in Debraux to the extent of permitting the taking of saliva and buccal swab samples from defendant Debraux’s body; allowing the OCME to compare defendant Debraux’s DNA profile as derived from the buccal swab sample with the DNA sample derived from the swabbing of the handgun found in defendant Debraux’s hotel room; and permitting the OCME to upload defendant Debraux’s DNA sample into its own local database for purposes of comparison with other DNA profiles already on file in that database. This court also denied defendant Debraux’s request to delay determination of the People’s discovery motion pending the completion of the suppression hearings in that case, but granted defendant Debraux’s motion for a protective order, to the extent that it precluded the testing of defendant’s profile by OCME or any other agency for disease or genetic disorders, and directed OCME not to upload defendant’s DNA profile into any of the state or federal DNA data banks within the Combined DNA Index System, or CODIS,
E. Rulings on Preclusion of Evidence and Request for Frye Hearing
Also on August 5, 2015, this court orally denied defendant Debraux’s cross motion to preclude the introduction of FST generated evidence at trial, or, in the alternative, for a Frye hearing, with written decision to follow.
II. Discussion
A. Consolidated Motions
The court will first address the common argument raised by both defendants that the lack of general acceptance of the FST as reliable in the forensic scientific community, because of its approach to accounting for stochastic effects, requires preclusion of expert testimony on FST results or, in the alternative, a Frye hearing.
The standard for admissibility of expert scientific testimony based upon novel methodology is “whether the accepted techniques, when properly performed, generate results accepted as reliable within the scientific community generally” (People v Wesley,
Two courts of coordinate jurisdiction have held extensive Frye hearings on the issue of FST reliability, and have reached divergent conclusions as the general acceptance of the FST as reliable in the relevant scientific community. In one of them, People v Rodriguez (Sup Ct, NY County, Oct. 24, 2013, Carruthers, J., indictment No. 5471/2009), on the basis of the testimony of eight witnesses and dozens of exhibits, including articles from scientific journals, multiple charts, tables and graphs (People v Rodriguez, slip op at 8 n 2), the court concluded that the FST is generally accepted as reliable in the forensic scientific community because it “rests firmly upon two pillars, Polymerase Chain Reaction-Short Tandem Repeat (PCR-STR) DNA analysis and the likelihood ratio.
In the other recent decision on FST reliability issued after a Frye hearing including testimony from expert witnesses, including some of those who testified in Rodriguez, People v
In the instant cases, as noted, the defendants do not challenge the FST to the extent that it is used to calculate likelihood ratios in DNA analysis. Neither do they challenge the use of Bayesian mathematical principles to make such calculations. Indeed, Collins, upon which the defendants rely, expressly states that no one disputes the use of Bayesian mathematical principles to calculate such probabilities (see
Both of the courts which have held Frye hearings on the FST have recognized that the FST’s approach to accounting for stochastic effects was designed to minimize the effect of random phenomena on the results obtained or conclusions drawn (see Rodriguez at 24 [“With obvious awareness of the advantage that the ‘(likelihood ratio) framework’ brings to the analysis of complex DNA mixtures, forensic scientists have developed several software programs, in addition to (the) FST, that enable (likelihood ratios) to be calculated which accommodate drop-out and drop-in”]; Collins,
The FST’s manner of accounting for stochastic effects, such as allelic drop-in and drop-out rates, may skew a likelihood ratio to one somewhat more favorable or somewhat less favorable to the prosecution or to the defense while not affecting the overall outcome of the inquiry whether it is more likely than not that a defendant was a contributor to a DNA mixture. For example, in People v Belle (
Viewed in this light, the manner in which the FST accounts for stochastic effects in its probability computations appears to this court to be akin to the calculation of a margin of error of the test results. Arguments as to the accuracy of this procedure and its effect on the ultimate test results go to the weight of the evidence, rather than to questions of its admissibility, however, given the conceded general acceptance of the conceptual underpinnings upon which it is based. As such, they may be addressed by cross-examination or through the use of defense expert witnesses (see People v Williams, Sup Ct, Bronx County, May 20, 2015, Moore, J., indictment No. 3445/2008,
Even assuming that the defendants in these cases are correct in their view that the Frye standard should be applied to the specific methodology employed by the FST to account for stochastic effects in calculating a likelihood ratio, however, their argument that the OCME is the only laboratory to use the FST does not require the holding of a Frye hearing in these matters. The manner in which FST assessment of such effects and rates is performed need not be unanimously endorsed by the relevant scientific community in order to be generally accepted as reliable (People v Middleton,
Additionally, for purposes of Frye analysis, a court may rely upon “previous rulings in other court proceedings as aid in determining” whether a technique has been generally accepted and whether evidence generated by use of that technique is admissible (People v LeGrand,
In another decision favoring the Rodriguez view, People v Belle, the court noted that “the FST’s overall methodology has been certified and accredited by the New York State Commission on Forensic Science and the National Forensic Science Technology Center” (id. at *4). The Belle court also observed that “the FST methodology utilizing the OCME’s allele drop-in and drop-out rates has been repeatedly validated and approved by experts in the field” (id.-, see People v Garcia, 39 Mise 3d at 489 [same]; People v Williams at 5 [same]; People v Rodriguez at 51 [same]). Numerous other courts have accepted the views of Rodriguez, Garcia and Belle (see e.g. People v Brown, Sup Ct, NY County, June 4, 2015, Zweibel, J., indictment No. 58/ 2012; People v Williams, Sup Ct, Bronx County, May 20, 2015, Moore, J., indictment No. 3445/2008; People v Johnson, Sup Ct, Kings County, Apr. 21, 2015, D’Emic, J., indictment No. 4728/ 2013; People v Colon; People v Whetstone, Sup Ct, NY County, June 17, 2013, White, J., indictment No. 5728/2012; People v
Furthermore, were this court to hold a Frye hearing on this issue, it would undoubtedly duplicate the testimony of many of the same expert witnesses who have already testified in the hearings held in Rodriguez and Collins, including several witnesses who testified in both hearings, and revisit questions already resolved by numerous other courts. To do so would be, in this court’s view, an unnecessary expenditure of judicial resources.
Finally, it warrants repeating that in a Frye analysis, it is not the role of the court to evaluate and appraise the merits of the scientific technique under consideration. As the Court of Appeals has repeatedly counseled, a proper Frye analysis involves “counting scientists’ votes” rather than “verifying the soundness of a scientific conclusion” (Parker v Mobil Oil Corp.,
Thus, this court is satisfied that the FST procedure for calculating likelihood ratios of an individual’s DNA in a mixed sample has been sufficiently shown to be generally accepted as reliable in the forensic scientific community, rendering a Frye hearing unnecessary as a precondition to the admission of such evidence at trial.
Defendant Merritt additionally seeks an in limine hearing on the admissibility of the FST results, claiming that their probative value would be substantially outweighed by their prejudice to him and misleading to the jury. Given that in this case, the other DNA sample from the back strap, side grips and front strap of the gun yielded a DNA mixture containing a 14-loci major male contributor to which defendant’s profile has proved to be a likely match, in that the DNA profile developed from that sample could be found in no more than one in greater than 6.8 trillion people, defendant Merritt’s claim of prejudice is baseless.
Accordingly, defendant Debraux’s cross motion and defendant Merritt’s motion to preclude expert testimony as to conclu
The court will now address the remaining motions made by the parties in defendant Debraux’s case only.
B. Motions for Testing and Protective Order in People v Debraux
Criminal Procedure Law § 240.40 (2) (b) authorizes a court in which an indictment is pending to grant, “subject to constitutional limitation,” an application by the prosecutor for an order compelling the defendant to provide non-testimonial evidence. Such evidence may include the taking of materials from his body, absent an unreasonable intrusion or the risk of serious physical injury (CPL 240.40 [2] [b] [v]).
The Court of Appeals has set forth the constitutional limitations on procedures involving corporeal evidence derived from a defendant’s body in its seminal decision, Matter of Abe A. (
Defendant Debraux’s challenge of the buccal swab testing sought by the People was based solely upon his assertion that the People have failed to satisfy the second prong of the Abe A. three-part test. Specifically, he maintained that there was no clear indication that relevant material evidence would have been found as a result of the OCME buccal swab testing the People sought here because the DNA profile of defendant
Turning to the constitutional caveat articulated by the Court of Appeals in Abe A., the crimes in question, namely, criminal possession of a weapon in the second (Penal Law § 265.03 [1] [b]) and third (Penal Law § 265.02 [1]) degrees, class C violent and class D felonies, respectively, are serious offenses. As the results of the DNA testing in question could either implicate or exonerate defendant, its importance to the investigation of this case is clear. Moreover, the taking of a saliva sample by means of a buccal swab is minimally intrusive, and the court is not aware of any less intrusive means of obtaining DNA evidence. Therefore, in balancing the seriousness of the crimes in question and the importance to the investigation of this case of the DNA buccal swab testing against the minimal intrusiveness of the test, the court finds that such testing is justified under these circumstances. Thus, defendant’s argument that buccal swab testing would violate his rights to privacy and protection against unreasonable searches and seizures under the state (NY Const, art I, § 12) and federal (US Const Amend IV) constitutions is unavailing to him.
Neither has defendant Debraux demonstrated any need for holding the decision on the People’s motion in abeyance pending the outcome of a pretrial suppression hearing.
Accordingly, for these reasons, the People’s motion to compel defendant Debraux to submit to buccal swab testing has been granted.
The court now turns to defendant Debraux’s cross motion for a protective order pursuant to CPL 240.50 limiting disclosure of the buccal swab testing results to the court, the prosecution and defense counsel, and prohibiting OCME from uploading of his known DNA profile into SDIS or NDIS or its own local DNA database.
To the extent that defendant Debraux seeks a protective order which would preclude OCME from comparing his known DNA profiles to DNA profiles found in any state or federal database, such an order is unnecessary. As the People assert in
Citing People v Rodriguez (
Nevertheless, OCME may ultimately acquire the ability to share with state or federal DNA databases DNA information concerning criminal defendants who, like defendant in this
As there is no statutory or constitutional impediment to OCME’s uploading defendant Debraux’s DNA profile, once developed from defendant’s buccal swab sample, into its own local database, this court declines to issue a protective order prohibiting OCME from doing so.
Therefore, defendant’s cross motion for a protective order is granted in part and denied in part as set forth in the order of this court dated August 5, 2015.
III. Conclusion
Accordingly, defendant Debraux’s cross motion and defendant Merritt’s motion to preclude the introduction of FST generated evidence at trial or, in the alternative, for a Frye hearing, are both denied.
As to the remaining motions in People v Debraux, this court adheres to its rulings as set forth in the order of this court dated August 5, 2015.
Notes
. The mathematical formulas utilized by the FST were devised by Reverend Thomas Bayes and have been in use for centuries (see People v Rodriguez, Sup Ct, NY County, Oct. 24, 2013, Carruthers, J., indictment No. 5471/2009, slip op at 7).
. Stochastic effects are random imperfections, often in the form of additions or subtractions, within the sample examined, that result in the appearance or nonappearance in DNA mixtures of certain genetic material, known as alleles.
. By letter dated July 16, 2015, Merritt’s counsel provided the court and the prosecution with copies of two recent Kings County decisions of courts of coordinate jurisdiction, both of which ordered Frye hearings on the grounds sought here. In People v Collins (
. CODIS is the generic term used to describe the Federal Bureau of Investigation’s (FBI) program of support for criminal justice DNA databases, as well as the software used to run these databases. The National DNA Index System or NDIS, which is considered a component of CODIS on the national level, contains DNA profiles contributed by federal, state and local participating forensic laboratories. If any of eight local laboratories in New York State, or LDIS, determine the DNA profile of a contributor with a degree of certainty, the DNA profile is uploaded to the New York State Police Forensic Index, which, together with the Convicted Offender Index jointly maintained by the New York State Police and the New York State Division of Criminal Justice Services, is known as SDIS. This information is uploaded and shared with other states via one of the two components of NDIS, namely, the FBI Forensic Index or the FBI Convicted Offender Index (New York State Division of Criminal Justice Services, http://www.criminaljustice.ny.gov/ forensic/dnabrochure.htm [accessed Sept. 16, 2015]).
5. As the Rodriguez court explained:
“[A likelihood ratio] is a ratio of two probabilities!,] • . . that the suspect is a contributor to a DNA mixture on the one hand (the prosecution scenario), and, on the other hand, that the suspect is not a contributor (the defense scenario) ....
“[Likelihood ratios] calculated by means of the FST software account for the probability of the occurrence during DNA analysis of the stochastic or random phenomena of allelic drop-out and drop-in. An allele is one of several alternative forms of a gene located at a specific locus. Drop-out occurs when an allele that is actually known to exist at a particular locus in a DNA sample is not found in the analysis. Drop-out may occur during testing of very small amounts on DNA or of DNA that has been substantially degraded. Drop-in occurs when an allele is detected during analysis that is known not to belong to the person or persons contributing to the sample” (People v Rodriguez at 5).
. The Collins court also reached a similar conclusion as to high sensitivity or low copy number (LCN) analysis, which is used upon samples with fewer than 100 picograms of DNA material (
. The Collins court reviewed four stochastic effects, including: drop-out; drop-in; “stutter,” “a common ‘echo’ effect appearing on the DNA profile— usually one allele before its true allele, or less frequently, just after,” and which “may show a peak as high or higher than the true allele”; and “peak heights,” referring to a phenomenon where “small amounts of DNA available for analysis may not yield consistent peak heights for the true alleles and may result in extraneous alleles at some loci that produce higher peaks than do the true alleles” (
. This court notes that three of the dissenting witnesses who testified in People v Collins were employed by the same laboratory, the University of North Texas Health Science Center, and that a fourth dissenting witness operated a defense consulting firm (see
. Additionally, the conclusion apparently reached by the Collins court, that the FBI and other laboratories do not employ the FST approach to accounting for stochastic effects because its methodology is deemed unreliable is, at the very least, subject to question, in light of the People’s uncontroverted proffer on tbe instant motion in Merritt that it is the extreme costliness of implementing the FST that has prevented the FBI and other laboratories from adopting the program (see People’s reply at 20-21).
