Troy D. Richardson v. United States
98 A.3d 178
D.C.2014Background
- On May 17, 2009, Tyrone Wheaton was fatally stabbed in the hallway outside his apartment; Troy Richardson was indicted for murder while armed and carrying a dangerous weapon (CDW).
- First trial: jury acquitted Richardson of first- and second-degree murder but deadlocked on voluntary manslaughter and CDW (mistrial on those counts). Second trial: Richardson convicted of voluntary manslaughter while armed and CDW.
- At the first trial the jury heard testimony that Richardson had previously told police about drug sales from Wheaton’s apartment (i.e., that he was a “snitch”); the second trial court excluded most of that “snitch” evidence as irrelevant.
- Richardson’s self-defense theory rested on his claim that he reasonably believed Wheaton knew he had snitched and would retaliate, making lethal force necessary; the excluded evidence would have supported both his credibility and the objective reasonableness of his fear.
- The D.C. Court of Appeals held the exclusion was an erroneous exercise of discretion and not harmless error, reversed the convictions, and ordered a new trial on both counts; the court also flagged, but did not finally resolve, evidentiary issues about admission of Richardson’s PCP use.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument (Richardson) | Held |
|---|---|---|---|
| Whether the trial court properly excluded evidence that Richardson had informed police about drug sales from Wheaton’s apartment ("snitch" evidence) | Evidence was irrelevant to Richardson’s self-defense claim because it did not prove what Wheaton actually believed | Exclusion prevented Richardson from showing why he reasonably believed Wheaton would retaliate and undermined his credibility — crucial to self-defense | Court: exclusion was erroneous; evidence was relevant to Richardson’s honest belief and its objective reasonableness; reversal and new trial required |
| Whether exclusion of the snitch evidence was harmless | Error did not substantially influence the verdict | Exclusion prevented presentation of a complete defense; reasonable probability that jury would have had reasonable doubt | Court: error not harmless under Heath/Kotteakos/Chapman; constitutional error that requires reversal |
| Proper harmless-error standard and test for excluded defense evidence | Apply non-constitutional Kotteakos standard when appropriate | Richardson urged Chapman (constitutional) review because exclusion impaired complete defense | Court applied Heath materiality test (reasonable probability the omitted evidence would create reasonable doubt) and concluded reversal required; same result under Kotteakos or Chapman given constitutional magnitude |
| Whether defendant must prove victim actually believed defendant was a snitch to claim self-defense | Government: proof that victim actually knew is required to link motive and threat | Richardson: need only show he honestly and reasonably believed victim knew and sought to retaliate | Court: Defendant need only show an honestly held, objectively reasonable belief; trial court erred by requiring proof that Wheaton actually knew |
