175 A.D.3d 158
N.Y. App. Div.2019Background
- Victim found dead in apartment with guitar amplifier cord around his neck; no forced entry or signs of struggle; items (laptop, PlayStation, orange duffle) missing.
- Defendant (Wakefield) was charged with first‑degree murder and first‑degree robbery; inmate witnesses reported admissions by defendant that he killed the victim and stole property.
- State collected defendant buccal swab; DNA from scene was analyzed by Cybergenetics using TrueAllele (a probabilistic, MCMC‑based software); results produced very high likelihood ratios linking Wakefield to DNA on the amplifier cord, T‑shirt collars, and victim’s forearm.
- Defendant moved to preclude TrueAllele evidence or, alternatively, for a Frye hearing on the method’s general acceptance; Supreme Court held a Frye hearing and found TrueAllele generally accepted and admissible.
- At trial, Perlin (Cybergenetics founder and TrueAllele author) testified extensively about the software, its algorithms, and the report; jury convicted; Wakefield appealed raising issues including Frye, sufficiency/weight of evidence, Confrontation Clause (source code), and other evidentiary rulings.
Issues
| Issue | People’s Argument | Wakefield’s Argument | Held |
|---|---|---|---|
| Admissibility under Frye of TrueAllele | TrueAllele is generally accepted; multiple validation studies and peer‑reviewed articles support reliability. | TrueAllele is novel; defendant should be allowed to exclude its results or require source code review to test reliability. | Frye hearing properly found TrueAllele generally accepted and admissible. |
| Sufficiency of evidence for robbery and murder in furtherance of robbery | DNA, missing property, and jailhouse admissions support that defendant stole property and killed victim during robbery. | Evidence insufficient to prove theft or that killing was in furtherance of robbery. | Viewing evidence in People’s favor, proof was legally sufficient; verdict also not against weight of evidence. |
| Confrontation Clause — need for TrueAllele source code disclosure | Not required; Perlin (author/witness) testified and was subject to cross‑examination; TrueAllele report is testimonial but Perlin was the declarant. | Source code (object producing the report) is the declarant; withholding it deprived defendant of confrontation and meaningful cross‑examination. | Report deemed testimonial, but Perlin — not the source code — was the operative declarant; no Confrontation Clause violation because Perlin testified. |
| Other evidentiary rulings (ID, witness impeachment, chain of custody) | Court properly admitted ID as confirmatory; allowed rehabilitation; chain issues go to weight not admissibility. | Challenged confirmatory ID, limits on cross of cooperating witness, chain of custody for sweatshirt/DNA. | Trial court rulings upheld: ID confirmatory, cross‑examination limits proper, chain issues affect weight not admissibility. |
