The fatal shooting of a middle-school student in Washington, DC has sparked backlash from the child’s family and activist groups as police increasingly face demands for answers.

Karon Blake, 13, was killed early Saturday by a man who told police he saw Karon “tampering with vehicles,” the Metropolitan Police Department said in a statement. Police Chief Robert Contee III declined to identify the shooter at a press conference Tuesday because he has not been charged with a crime.

The shooting has sparked backlash from Karon’s family, local officials, activist groups and community members who demanded the shooter be identified and arrested at a meeting that drew more than 300 people.

Mayor Muriel Bowser said she was “incredibly saddened” by the shooting at a press conference Monday.

“We would rather be talking about a 13-year-old going to school today than to talk about him being killed on one of our streets,” she said.

What happened during the shooting?

Early Saturday morning, a man “heard noises and observed someone that appeared to be tampering with vehicles” and went outside with a registered firearm to investigate, according to statement from police. During an interaction between the two, the man shot Karon, police said.

Police responded to the scene of a shooting and found Karon suffering from what appeared to be gunshot wounds, the statement said. He was hospitalized and later pronounced dead, police said.

Who was Karon Blake?

Karon was a “quiet and inquisitive scholar who loved fashion and football,” Brookland Middle School principal Kerry Richardson said in a letter to the school’s staff, according to NBC Washington. She said Karon is survived by his mother and three younger siblings, the outlet reported.

“Although he loved his neighborhood, he loved Brookland MS (the faculty & his peers) and the structure it presented to him even more,” Richardson wrote.

Who shot Karon Blake?

Bowser in a Wednesday press conference confirmed the shooter is a city employee who has been placed on administrative leave, and is not a police officer or otherwise involved in public safety.

Contee declined to identify the shooter Tuesday. He said the man who shot Karon, who is Black, is an “African American” who is not a law enforcement officer and has a license to carry a concealed weapon.
