306 A.3d 126
D.C.2023Background
- Daniel Geter was convicted of assault and firearm offenses following the nonfatal shooting of Jessica Little in Washington, D.C.; the jury heard he was at the scene and there was tension between him and Little prior to the shooting.
- Physical evidence connected to Geter included a sweatshirt found at the scene with DNA consistent with him, and surveillance video showing an individual in clothing matching what he wore that night.
- Detectives identified Geter in the surveillance footage based solely on clothing and shoes, with no prior acquaintance or substantial familiarity.
- A firearms and toolmark examiner testified that shell casings from the scene came from the gun recovered at the scene, stating a direct match.
- Geter appealed, arguing the expert's certainty in linking casings to the gun, and the detectives’ identification testimony, were improperly admitted.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Admissibility of firearms expert’s testimony linking casings to the gun | Geter: Absolute match testimony lacks scientific basis per precedent | Government: Examiner didn’t state 100% certainty or exclude all other guns | Court: Testimony was error; unqualified identification not supported by science |
| Admissibility of detectives’ lay identification of Geter in video | Geter: Detectives lacked sufficient personal familiarity for lay ID | Government: Identification based on investigative role and distinctive clothing | Court: Testimony was error; lay opinion requires substantial prior familiarity |
| Whether errors warranted reversal under plain error | Geter: Cumulative errors undermined fairness of trial | Government: Other evidence overwhelmingly supports conviction | Court: Errors did not affect outcome given strength of other evidence |
| Whether two PFCV convictions should merge | Geter: Convictions arose from single act with one weapon | Government: Concedes merger required | Court: Convictions should merge, remanded to vacate one |
