On the afternoon of October 1, 2014, 18-year-old Johnie Lee Resper was found with gunshot wounds on Adams Street NE in Northeast Washington, D.C., near 3rd and Adams Streets. Emergency responders discovered Resper, a Black male and resident of Upper Marlboro, Maryland, at about 3:04 p.m.; he was grievously wounded and later died from his injuries.

Detectives identified a teenage suspect and in November 2014 arrested 17-year-old Ahmal McGainey, who was charged as an adult with second-degree murder while armed. Authorities alleged the shooting was retaliatory; court documents say McGainey’s friend had been stabbed and assaulted by Resper and two others just before the fatal shooting. McGainey reportedly told police he did what he had to do.

Investigators linked McGainey to the killing after recovering a Colt .38 Special revolver 17 days after the shooting following a hit-and-run involving McGainey and his brother; forensic analysis reportedly matched that gun to Resper’s killing. Does anyone have information about Johnie Lee Resper, the events that day, or additional details that could help clarify what happened?
