DNA evidence has linked two of the teenagers charged in the shooting death of a University of Massachusetts student who was working as a congressional intern in Washington, D.C. last summer, prosecutors alleged.
Government attorneys told Washington, D.C. Superior Court Judge Danya Dayson during a Friday status hearing that testing on shell casings recovered at the scene produced an “overwhelming statistical match” to Jailen Lucas, and that DNA also ties Kelvin Thomas to the shooting.
The two suspects, who were both 17 at the time of the shooting, are charged as adults with first-degree murder while armed in the killing of Eric Tarpinian-Jachym, 21, of Granby, Massachusetts.
