The white former Fort Worth, Texas, police officer accused of gunning down a black woman in her own home was charged with murder for the slaying on Monday, authorities said.

Aaron Dean, who resigned after Saturday’s killing, was booked in the Tarrant County jail Monday afternoon, according to jail records.

Dean allegedly shot Atatiana Jefferson through a window of her home while responding to a report of an open door, authorities said.

The shooting was captured on Dean’s body camera, which shows the cop approach the window of the home with his gun drawn and shout “put your hands up!”

Dean then squeezed off a single shot, which struck 28-year-old Jefferson, according to the footage.

Police were called to the house by a neighbor who saw Jefferson’s door ajar and requested a welfare check. There was no indication the officers knocked on the front door when they responded, and the window Dean allegedly fired through was only accessible through her fenced-in backyard.

Dean resigned Monday after interim police Chief Ed Kraus said he would have fired him if he did not offer his resignation.

Ashley Carr, Jefferson’s heartbroken sister, remembered her Monday as a “smart, ambitious, kind person with a nurturing spirit.”
