A Fort Worth , Texas, police officer fatally shot a black woman in her own home early Saturday while responding to a neighbors request for a welfare check on the residence, authorities said.

Police identified the officer responsible for killing Atatiana Jefferson, 28, as a white male who has been with the department since April of 2018. His name has not yet been released. He has been placed on administrative leave pending the outcome of an internal investigation, and is scheduled to be interviewed Monday by the Major Case Unit, police said.

Jefferson was shot through a window around 2:30 a.m. as officers responded to a non-emergency call from neighbor James Smith who said the front door of the home was open with the lights on, the Fort Worth Police Department said in a statement and press conference on Sunday evening.

The officer observed a person through a rear window in the house and fired a shot at that person, Police Chief Edwin Kraus told reporters. The officer did not announce that he was a police officer prior to shooting. What the officer observed and why he did not announce police will be addressed as the investigation continues.

Officers then went inside and provided emergency medical care to Jefferson, but she was pronounced dead at the scene, police said. The statement said Jeffersons 8-year-old nephew was inside the room at the time of the shooting.

Police released video from a body camera worn by the officer who fired the shot, which shows him approaching the front of the house and peering inside. The footage shows storm doors were closed, but two main doors behind them were open. Lights inside the house were on, and at least one car was parked in the driveway.

The officer can be seen entering the backyard, turning to the left and shining a flashlight through a window. He suddenly grabs for his gun, points it at the window and shouts, Put your hands up! Show me your hands! before immediately opening fire.
