146 A.D.3d 458
N.Y. App. Div.2017Background
- Defendant Deron Boone was convicted of third-degree assault (2011) and, after retrial, convicted of second-degree criminal possession of a weapon (2013) and sentenced as a second felony offender to 14 years. Both convictions were affirmed.
- Defendant sought to admit expert testimony on false confessions; the trial court initially ordered a Frye hearing but, after reargument, denied admission and declined a Frye hearing.
- Defense limited its proffered expert testimony to situational (interrogation-related) factors and did not present an expert affidavit showing relevance to Boone’s interrogation.
- Defendant sought to impeach the interrogating detective with alleged bias shown in Facebook posts; the court excluded those posts as speculative and remote.
- The jury received thorough voluntariness instructions; the court declined an attenuation instruction regarding a prior unwarned confession.
- Defendant raised claims of double jeopardy (retrial after mistrial), weight of the evidence, and ineffective assistance; the court rejected these on the merits or as unreviewable on direct appeal.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Admissibility of false-confession expert testimony | People argued proffer lacked relevance to this defendant/interrogation under Bedessie | Boone sought to admit expert on situational factors of false confessions | Motion court denial affirmed: proffer did not show relevance to Boone’s interrogation; Bedessie does not require experts to address both dispositional and situational factors |
| Need for Frye hearing on expert testimony | People opposed Frye absent a proper proffer | Boone sought Frye after initial order | No Frye hearing required because defendant failed to show admissibility/relevance |
| Impeachment of detective via Facebook posts | People argued posts had no specific connection to defendant or his group and were speculative | Boone argued posts showed implicit bias warranting impeachment | Exclusion affirmed: posts too remote/speculative to show bias or violate confrontation rights |
| Jury instruction on attenuation of an unwarned prior confession | People maintained voluntariness instructions were sufficient; attenuation not warranted here | Boone sought attenuation charge for prior unwarned confession | No attenuation instruction required; omission not reversible error |
