United States v. Kevin Asher, 910 F.3d 854

Background

Defendant Kevin Asher, a deputy jailor, was charged with (1) deprivation of civil rights under 18 U.S.C. § 242 and (2) falsifying a record under 18 U.S.C. § 1519 for allegedly beating inmate Gary Hill and filing false reports to cover it up.
The government notified it would introduce evidence of a separate prior incident (Dustin Turner) in which Asher and co‑defendant Hickman allegedly assaulted a restrained inmate and fabricated reports to conceal the assault.
At a pretrial hearing the district court found the prior incident proved, concluded it was offered for a proper purpose (intent), and ruled the evidence admissible under Rule 403 despite Asher offering a conditional stipulation to intent (i.e., he would concede intent if the jury found he committed the charged assault).
The jury heard both incidents with limiting instructions that the Turner evidence could be used only to prove intent; Asher was convicted and sentenced to 108 months’ imprisonment.
On appeal Asher argued the district court abused its discretion admitting the prior‑act evidence because its modest probative value (intent was provable from the charged conduct itself) was substantially outweighed by the unfair prejudicial risk of propensity reasoning.
The Sixth Circuit agreed the admission was an abuse of discretion and that the error was not harmless, vacated the convictions and sentence, and remanded for a new trial.

Issues

Issue	Plaintiff's Argument	Defendant's Argument	Held
Admissibility of prior‑act evidence to prove intent under Fed. R. Evid. 403	Gov’t: Prior Turner incident is highly probative of Asher’s specific intent because of similarity and temporal proximity; limiting instruction mitigates prejudice	Asher: Prior act is highly prejudicial and largely redundant because the charged conduct itself suffices to prove intent; offered conditional stipulation to intent	Court: Admission was an abuse of discretion—probative value was only incremental and danger of unfair prejudice (propensity inference) was high; evidence should have been excluded
Effect of defendant’s conditional stipulation to intent	Gov’t: Free to prove its case with evidence it chooses; stipulation does not automatically bar admissible proof	Asher: Stipulation would eliminate need for highly prejudicial prior‑act evidence	Court: Stipulation was a factor; where intent is subsumed in charged conduct and alternative proof exists, stipulation reduces probative value and weighs against admission
Sufficiency of limiting instruction to cure prejudice	Gov’t: Limiting instruction and pattern jury charge prevent misuse	Asher: Instructions insufficient to avoid propensity inference given strong similarity	Court: Instruction insufficient to dispel the risk; jurors likely to generalize prior bad act into propensity evidence
Harmlessness of error	Gov’t: Evidence of guilt was strong; any error harmless	Asher: Prior‑act evidence could have substantially swayed jury given credibility dispute about Asher’s role	Court: Error not harmless—because credibility dispute over Asher’s involvement remained, cannot say admission did not substantially sway verdict
