989 F.3d 629
8th Cir.2021Background
- Night of partying at Zephier’s home on Yankton Sioux Reservation; A.Z. later alleged Zephier raped her after she fell asleep on his couch; Zephier claimed consensual sex and also admitted prior rape accusation during a jailhouse interview.
- FBI Agent Mertz and tribal investigator interviewed Zephier after Miranda warnings; Zephier asked for a lawyer but officers stopped questioning; Mertz then presented a search warrant authorizing a buccal swab and the officers executed an interview during which Zephier made inculpatory statements.
- Zephier was indicted for aggravated sexual abuse in Indian country, moved to suppress his jailhouse statements, sought to exclude government expert testimony on victim behavior, and sought to admit evidence that A.Z. had been sexually assaulted previously.
- District court denied suppression, admitted the government’s expert (Krista Heeren‑Graber) to explain common post‑assault behaviors, and excluded evidence of A.Z.’s alleged prior sexual assault under Rule 412.
- A jury convicted Zephier and he was sentenced to 180 months; on appeal he argued (1) the buccal‑swab remark was interrogation after invocation of counsel and (2) the combination of admitting expert testimony while excluding evidence of a prior assault denied his right to present a complete defense.
- The Eighth Circuit affirmed the admissibility of the buccal‑swab statement but held that admitting the expert while barring evidence of a prior sexual assault was constitutionally disproportionate and reversed for a new trial.
Issues
| Issue | Zephier’s Argument | Government’s Argument | Held |
|---|---|---|---|
| Whether officers violated Edwards/Davis by continuing interrogation after Zephier invoked counsel when Agent Mertz announced he had a warrant to take buccal swabs | Zephier: He unambiguously invoked counsel and any further statements by police (including announcing the warrant) were interrogation that required termination | Government: Officers ceased questioning after invocation; the statement describing the search warrant was a factual, non‑interrogative statement about a legitimate police procedure | Held: No suppression. The warrant‑announcement was a factual statement not reasonably likely to elicit incriminating responses, so not interrogation under Innis/Muniz; suppression denied. |
| Whether admitting expert testimony about typical sexual‑assault victim behavior while excluding evidence that the alleged victim suffered a prior sexual assault violated the defendant’s right to present a complete defense | Zephier: Expert testimony bolstered victim credibility; excluding evidence of a prior assault prevented him from offering a plausible alternative explanation for the victim’s behavior | Government: Rule 412 exclusion is proper to protect victims; prior assault was remote and other evidence of guilt was strong | Held: Reversed. The combination of the expert’s bolstering and the categorical exclusion of prior‑assault evidence was disproportionate and impaired Zephier’s constitutional right to present a defense; remand for a new trial. |
