Wynn v. United States, 241 A.3d 277

On October 20, 2016 Kevin Smith was assaulted; he testified he owed synthetic‑marijuana debt to Irik Wynn (appellant) and Michael Benjamin and identified Wynn as his assailant.
Benjamin gave a post‑arrest recorded interview to MPD Detective Howard admitting he confronted Smith and acknowledging calls from his cellphone to an unnamed person shortly after the confrontation.
Wynn moved to sever pretrial, arguing Benjamin’s statements (Benjamin did not testify) would violate his Sixth Amendment right under Bruton; the court denied severance and admitted a redacted transcript replacing Wynn’s name with neutral terms.
Immediately before the redacted transcript was read, the prosecutor elicited Detective Howard’s testimony that Benjamin knew Wynn—linking the redacted “other guy” to Wynn.
Wynn’s counsel was prevented from cross‑examining Smith about (1) an October 11 assault by a man named Cory and (2) other community debts Smith allegedly owed, because the court found the proffers insufficient.
The jury convicted Wynn of assault with a dangerous weapon; the D.C. Court of Appeals reversed, holding the redacted interview was impermissibly linked to Wynn under Bruton/Gray and the error was not harmless, but upheld the limitation on cross‑examination for lack of an adequate proffer.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Admission of Benjamin’s redacted interview (Confrontation Clause/Rule 14)	Wynn: admission of Benjamin’s out‑of‑court statements violated his Sixth Amendment right and Rule 14 because Benjamin did not testify; severance or proper redaction required.	Govt: redactions and limiting instruction cured any Bruton risk; the transcript was not facially incriminating.	Reversed: The prosecutor elicited Detective testimony that blatantly linked the redacted “other guy” to Wynn (Gray/Bruton); redaction failed and error was not harmless.
Limitation on cross‑examination of Smith for bias (prior assault by "Cory" and alleged other debts)	Wynn: barring inquiry prevented probing witness bias and violated confrontation.	Govt: Wynn made no adequate proffer establishing a genuine belief/well‑reasoned suspicion of bias; issues were speculative (Winfield/Howard).	Affirmed: Court did not abuse discretion—Wynn failed to proffer facts sufficient to permit the proposed bias or third‑party‑perpetrator inquiry.
