257 A.3d 524
D.C.2021Background
- Feb. 12, 2016: three masked men fired into Wrenn’s Barbershop, wounding Andre Wilkinson and his 22‑month‑old son; witnesses saw three masks, two sets of shots, and a white SUV depart the scene.
- Surveillance and ATF footage tracked a white SUV from a parking lot toward the barbershop and away afterward; officers identified appellants Terrence Atchison and Barry Bloomfield as two passengers in that SUV from video stills.
- Both appellants were wearing CSOSA GPS ankle monitors on the day of the shooting; CSOSA shared GPS data with MPD. GPS expert testified the devices have ~50‑foot accuracy and environmental factors can worsen precision.
- Additional evidence: ski mask with possible DNA link to Bloomfield; ballistics showing three guns used; eyewitnesses could not identify the shooters behind masks.
- Appellants were convicted of multiple firearms and assault charges; they appealed raising Fourth Amendment, evidentiary (neighborhood‑feud and excluded rebuttal evidence), and sufficiency claims.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| 1. Suppression of CSOSA GPS data (Fourth Amendment / expectation of privacy) | GPS monitoring and CSOSA’s sharing with MPD violated Fourth Amendment and privacy | CSOSA monitoring is a "special needs" search of supervisees; sharing with police was foreseeable (Jackson controlling) | Denial of suppression affirmed; Jackson controls—monitoring and sharing lawful as special‑needs of supervision |
| 2. Admissibility of inter‑community hostility evidence (neighborhood feud) | Generalized neighborhood‑feud evidence was irrelevant and unduly prejudicial; no link between appellants and past violent acts | Evidence provided motive/context (made presence in victim’s neighborhood probative); government limited to geographic rivalry, not gang labels | Admission was within trial court discretion: relevant and not substantially more prejudicial than probative |
| 3. Exclusion of defense evidence of intra‑community violence (Wilkinson’s hospital arrest/burglary) | Excluding evidence rebutting government’s feud theory violated due process and right to present complete defense | Proffered evidence was third‑party perpetrator evidence regulated by Winfield; defense failed Winfield showing | Court erred treating proffer as Winfield evidence (it was permissible rebuttal), but error was harmless beyond a reasonable doubt given strength of other evidence |
| 4. Sufficiency of evidence to prove participation / aiding and abetting | Evidence was insufficient: eyewitnesses did not identify appellants as shooters; GPS expert could not place them at the doorway; presence/association insufficient | GPS, video, flight, vehicle identification, mask DNA, and circumstantial proofs allowed inference appellants were among three masked shooters or aided/abetting with purposive attitude | Evidence sufficient: jurors could reasonably infer appellants participated (surveillance/transport/flight) and had requisite mens rea for aiding/abetting; convictions affirmed |
