A man was charged Tuesday with second-degree murder while armed in connection with the fatal shooting of a 13-year-old in Washington, DC, police announced Tuesday.

Jason Lewis, a longtime Parks and Recreation Department employee police say fatally shot Karon Blake, turned himself in Tuesday morning, Metropolitan Police Chief Robert Contee III said at a press conference.

“Here we have a kid who’s dead who shouldn’t be,” Contee said. “Now again we have to go through the course of the judicial process.”

The arrest of Lewis comes nearly three weeks after the fatal shooting sparked backlash from Blake’s family, local officials and community members who demanded the shooter be identified and arrested. Video evidence was crucial to investigators, who had to “overcome” Lewis’ self defense claim, Contee said.

Lewis. 41, was ordered held without bond until a Feb. 13 court appearance. His attorney Lee Smith told the Washington Post the shooting was a tragedy, but said “the public will see, no crime was committed here.” USA TODAY has reached out to Smith for comment. 

What happened during the shooting?

Jan. 7, a man “heard noises and observed someone that appeared to be tampering with vehicles” and went outside with a registered gun to investigate, according to a statement from police. Contee confirmed Tuesday that a group of young men were using flashlights and “going into” cars near Lewis’ residence.

Lewis left his home and fired a shot at a “getaway vehicle” that was parked nearby, Contee said.

“That’s where things really unravel,” he said. “That kind of put the chain of events into place.”

Video footage appears to show Blake and another unidentified person running toward the vehicle when it reversed into an alley and crashed, Contee said. Blake then ran toward Lewis, although it’s unclear if he saw him in the darkness, and Lewis shot Blake, Contee said.
