Jefferson was playing videogames with her nephew early Saturday morning, October 12, 2019. The 28-year-old black woman was fatally shot in her home by a white Fort Worth police officer. The officer, Aaron Dean, 34, ended up resigning and was charged with murder.
A neighbor, concerned that the house's front door was ajar, called a nonemergency police line to ask that a welfare check be conducted. Jefferson was alerted to a noise outside her home and pulled out her handgun, which she legally owned. Bodycam footage showed two officers peering into Jefferson’s house through a pair of screen doors, then walking stealthily into the backyard. Dean shined a flashlight into a closed window and, without identifying himself as police, shouted, “Put your hands up! Show me your hands!” A split-second later, he opened fire, killing Jefferson. There is no indication in the footage that he saw Jefferson holding the gun.
