Body-cam footage released in fatal shooting of 17-year-old by Park Police in Washington, DC.

Body-cam footage released by the U.S. Park Police shows an officer fatally shooting a 17-year-old in Washington D.C. last month after the officer climbed into the back of a vehicle to detain the teen and was still inside when he drove away. The footage reveals officers strategizing for how to take him into custody as he sat, apparently asleep, in the front seat of a vehicle they believed to be stolen. The Martin family is calling for the Park Police officers to be publicly identified and for the one who killed her son to be prosecuted and terminated.
