Dean and another officer were responding to an early-morning house call after a neighbor became concerned when they noticed the front door of a home, which belonged to Jefferson's mother, was left ajar and requested a welfare check.
Jefferson had been babysitting her 8-year-old nephew inside and playing video games. According to police and body camera footage,
Dean failed to identify himself before firing his weapon, striking Jefferson.
The bodycam video released publicly shows the perspective of an officer outside the home, peering into a window using a flashlight and spotting someone inside standing near a window and telling her, "Put your hands up — show me your hands." A single shot is fired seconds later.
