77 A.3d 505
N.J. Super. Ct. App. Div.2013Background
- Defendant was arrested in connection with a sexual assault and murder; two codefendants confessed but did not implicate him; defendant later confessed while jailed on an unrelated warrant.
- Defendant contended his post-arrest statement was unreliable and involuntary because he was experiencing severe heroin withdrawal when he confessed.
- At an N.J.R.E. 104 hearing the trial court allowed a defense psychiatrist to testify that defendant was addicted and in withdrawal and that withdrawal symptoms could make an addict vulnerable to false confessions, but prohibited the expert from opining that this particular confession was false.
- The State appealed the trial court’s allowance of the psychiatric expert at a forthcoming Miranda hearing and at trial.
- The Appellate Division affirmed, holding expert testimony about a diagnosed condition (here heroin addiction/withdrawal) that explains susceptibility to false confession is admissible, subject to limits to avoid usurping the jury’s credibility role.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Admissibility of psychiatric expert on addiction/withdrawal to explain confession reliability | State argued no scientific basis to link addiction/withdrawal to false confessions and that such testimony departs from precedent disallowing false-confession experts | Defense argued expert testimony is necessary to explain how withdrawal could impair reliability and allow meaningful attack on confession (Crane right to present circumstances) | Expert testimony about diagnosed conditions and hypothetical effects on vulnerability is admissible under N.J.R.E. 702 if reliable and helpful; but expert cannot opine that the specific confession was false |
| Scope of permissible expert testimony (general phenomenon v. defendant-specific diagnosis) | State urged exclusion of testimony about false confessions generally | Defense sought to explain defendant's specific mental/physical state (heroin withdrawal) and how it could affect his responses | Court distinguished King (diagnosed disorders allowed) from Free/Rosales (generalities disallowed); allowed testimony tethered to a recognized diagnosis and individualized facts, but barred credibility/usurpation opinions |
| Use of hearsay within expert’s opinion | State concerned expert would parrot defendant’s unproven statements about interrogation to jury | Defense relied on interviews, jail/medical records and interview observations as bases for expert opinion | Expert may rely on hearsay under N.J.R.E. 703 to form opinion, but jury cannot consider those statements for truth; if opinion depends on unproven hearsay, jury should be instructed to consider its probative value accordingly |
| Trial court’s duty re: limiting instruction and future evidentiary rulings | State argued risk of jury confusion/prejudice without tight limits | Defense argued Miranda hearing and expert testimony needed to present full defense | Court directed limiting instructions, left specific evidentiary rulings to trial judge, and noted Miranda hearing may preview use of expert testimony; if confession suppressed, expert testimony issues moot |
