District of Columbia Court of Appeals

Wallace & Layne v. United States

August 27, 2026

Summary

The D.C. Court of Appeals affirmed the convictions of Elliott Wallace and Antoine Layne arising from a traffic stop that yielded firearms and drugs. The court held that the trial court did not abuse its discretion in qualifying MPD Officer Scott Brown as a narcotics expert and allowing him to testify about the drug 'boot' (N,N-dimethylpentylone), finding his deficiencies went to weight, not admissibility. It also held the trial judge's clarifying questions of witnesses were not plain error, and that the evidence was sufficient to support Wallace's PWID conviction. Judge Deahl concurred in the judgment in part and dissented in part, arguing Layne's PWID and PFCV convictions rested on insufficient evidence.
