813 F.3d 619
7th Cir.2015Background
- Antonio West was arrested after police found a stolen television and, during a consensual search of an address West gave, recovered a second TV and a loaded M1 carbine in the attic of his late father’s house. West later told officers the rifle was his.\
- West has documented low IQ (verbal score ~73) and significant mental illness; a defense forensic psychologist (Dr. Dinwiddie) administered the Gudjonsson Suggestibility Scale showing high suggestibility.\
- At a suppression hearing the district court denied a motion to suppress West’s custodial statements and the search consent, finding West competent to waive Miranda rights and that the waiver and consent were knowing and voluntary.\
- For trial the defense sought to call Dr. Dinwiddie to: (1) help the jury assess the reliability of West’s confession, (2) negate the mens rea element, and (3) explain West’s courtroom/testimony demeanor. The government agreed the expert could testify to confession reliability but objected to the other uses.\
- The district judge excluded Dr. Dinwiddie’s testimony entirely (citing relevance and risk of inviting an insanity defense) and excluded related nonexpert evidence (cousin’s testimony and disability on ID). The jury convicted West of felon-in-possession and he received an ACCA-enhanced sentence.\
- The Seventh Circuit held the expert testimony was wrongly excluded as to confession reliability, reversed, and remanded for a new trial; it instructed reconsideration of nonexpert evidence on remand.
Issues
| Issue | West's Argument | Government's Argument | Held |
|---|---|---|---|
| Admissibility of expert testimony on confession reliability | Dr. Dinwiddie’s testimony about West’s low IQ, mental illness, and suggestibility is relevant to assess trustworthiness of West’s inculpatory statement | Agreed expert testimony is admissible only on reliability; opposed other proposed purposes | Reversed: expert testimony was admissible on reliability and exclusion was erroneous |
| Admissibility of expert testimony to negate mens rea / explain demeanor | Testimony could show incapacity to form requisite intent and explain demeanor if West testifies | Argued this was effectively an insanity defense and improper under Rule 704(b) | Denied for those purposes; court affirmed exclusion for intent/demeanor uses (judge did not abuse discretion on those grounds) |
| Admissibility of nonexpert proof of disability (cousin; ID card) | Nonexpert evidence supports jury assessment of confession reliability and residence; admissible with expert context | Court excluded as irrelevant and likely to confuse/jurors | Closer call: exclusion likely erroneous when paired with expert testimony; should be reconsidered on remand |
| Harmless-error assessment given reliance on confession | Exclusion of expert evidence undermined jury’s ability to assess confession reliability; not harmless because case rested largely on confession | Government contended other evidence (ID, checkbook) tied West to residence and undermined suggestibility claim | Held exclusion was not harmless; new trial required |
