A Washington, D.C. government employee accused of shooting and killing 13-year-old Karon Blake earlier this month has turned himself in to police, officials said Tuesday, while an arrest affidavit revealed the boy's final words after being shot.

Jason Lewis, 41, was charged with second-degree murder while armed after an investigation and presentation of the case to a grand jury, Metropolitan Police Department chief Robert J. Contee III said in a briefing. 

Lewis turned himself in on Tuesday morning and remains in police custody, Contee said.
