"Drop the gun! Drop the gun! Drop the gun now!" a Cottonwood Heights police sergeant can be heard in body camera video yelling at the teen suspect. Just moments later, the officer fires a single shot, hitting the 17-year-old boy in the abdomen. "Sir, why did you reach in your pants?" the officer asks the boy in the video as he handcuffs him. The videos from an early morning officer-involved shooting on Sept. 3 were released Monday by the Cottonwood Heights Police Department. The incident began as a routine traffic stop at 3 a.m. But when the two occupants of a vehicle sped away, it resulted in a chase that ended when the teenage driver crashed his car on I-15 near 1300 South. In his body camera video, the sergeant, whose name has not been released, is heard telling dispatchers that a male and a female juvenile are out of the car and running down the off-ramp at 1300 South. As the sergeant follows, he finds the teens under the freeway overpass at 1300 South. The girl has stopped running. But the 17-year-old boy is still walking. The officer, believing he saw a gun, gets out of his patrol car yelling at the boy to "drop it." Although a gun was recovered, investigators have not said whether the teen was actually holding a gun in his hand. "Drop it now. Get on the ground. Get on the ground now or I’ll shoot you,” the officer orders at gunpoint. As the teen sits on the ground and raises his hands above his head, the officer orders him to roll over onto his stomach. It's at that point that the boy seems to be moving his hands near his waistband. "Do not move. Don’t move," the sergeant yells. "I’m not moving sir," the teen replies. "Don't. Don't. Don't," the sergeant continues to yell in quick succession before firing one shot. After firing the shot, the officer orders the teen to "stay down." He then radios to police dispatch, "Suspect reached for his waist, shots fired." "What were you reaching for?" the officer asks the boy. The boy is still conscious and alert after being shot and is able to communicate in the video with the sergeant and backup officers who arrive on scene. After putting the boy in handcuffs, the officers immediately start giving the boy medical attention.
