The Justice Department has opened a federal civil rights probe into the death of Dalaneo Martin, a Black 17-year-old who was fatally shot by a U.S. Park Police officer in Washington, D.C., last month. The investigation was announced after Tuesday’s release of police body-camera video showing the March 18 shooting. The video shows officers investigating what they called a “suspicious vehicle” with Martin sleeping behind the wheel. An officer opens a rear door of the SUV and issues the command, “Police! Don’t move!” Martin accelerates with an officer in the back seat; the officer then fires multiple times before the SUV crashes into the side of a home. A medical examiner later reported Martin was shot six times and died instantly. His mother, Terra Martin, spoke to reporters on Wednesday.

Terra Martin: “I want the officer’s name released immediately. I want him arrested. I want him to stop getting paid while he murdered my son and still home with his family, not doing no work and getting paid for murder.”
