A federal civil rights investigation has been opened into the police killing of a 17-year-old in Washington, D.C., after body camera footage of the fatal shooting was released Tuesday.

On March 18, Metropolitan Police Department and U.S. Park Police officers found Dalaneo Martin asleep in a car police believed to be stolen, officials said. Park police got into the car and, after a struggle, Martin drove away with an officer still in the backseat. That officer shot Martin multiple times, body camera video shows, before Martin crashed the car into a house. 

The U.S. Attorney’s Office called the footage of the shooting “extremely upsetting.”

“The loss of a life is always tragic but is especially heartbreaking when it involves a child,” the office said in a statement. “In coordination with the FBI Washington Field Office, the United States Attorney’s Office has opened a civil rights investigation into the circumstances leading to Mr. Martin’s death.”

What does the body camera footage show?

MPD officers responded to a report of a suspicious vehicle and found Martin asleep in the driver’s seat of a car police said was reported stolen earlier that month, according to police. The engine was running and the ignition was damaged, police said.

Additional MPD officers and two Park Police officers arrived to help detain Martin, the department said. The group can be heard discussing how to remove Martin from the car in body camera footage released by MPD.

“The back window is just a plastic. I’m going to try to cut that out quietly, unlock the door,” an MPD officer can be heard saying. “If he doesn’t get startled, doesn’t wake up, then we’re going to try to get in there, grab him before he puts that car in gear.”

After further discussion of where Martin’s hands are, the officer says police should wait to see if Martin “gets startled” after he tries to unlock the door. “If he does, if he takes off, just let him go,” the officer says.
