The D.C. government employee who shot and killed 13-year-old Karon Blake turned himself in Tuesday to face a second-degree murder charge, D.C. police chief Robert Contee said.

Blake yelled “I’m sorry,” “I am a kid” and “I am only 12” numerous times as the suspect fired in his direction, according to court documents that described surveillance video. Contee said video was integral to the investigation.

Jason Lewis, 41, is charged with second-degree murder while armed for shooting Blake on Quincy Street NE in the Brookland neighborhood about 4 a.m. on Saturday, Jan. 7, court documents say.

Lewis heard noises and saw someone who appeared to be “tampering with a vehicle.” The resident stepped outside armed with a legally registered gun, and after an interaction with the teen, opened fire, according to police. Neighbors said they heard four to five gunshots during the incident.

Police said the man performed CPR on Blake after shooting him. Blake died a short time later at a hospital.
