Fairfax County, Virginia, police on Monday released bodycam video of an officer fatally shooting a 6'5" woman last month who slashed the officer's face and kept advancing on him despite his repeated warnings for her to stop.

Police said the officer just after 10 a.m. Sept. 16 responded to a residence in the 11800 block of Sunrise Valley Drive in Reston for a welfare check following a request from a mental health professional who said 33-year-old Sydney Wilson was in an agitated state. Reston is about a half hour northwest of Washington, D.C.

The officer retreated and tried to de-escalate the situation with repeated verbal commands for Wilson to 'back up!'

The officer, who was trained in crisis intervention, knocked on Wilson’s door, police said, adding that Wilson opened and immediately closed the door. The officer continued to try to speak with Wilson for two minutes and 45 seconds, explaining he wanted to check on her welfare, police said.

When Wilson opened the door again, she was holding a knife and immediately assaulted the officer outside the residence, police said.

Soon after the deadly incident, police said Wilson had multiple encounters with officers this year, and Fairfax County Police Chief Kevin Davis described Wilson as standing six feet, five inches tall and weighing around 330 pounds, WDVM-TV reported.

According to Wilson's obituary, in 2009 she accepted a full scholarship to Georgetown University where she played basketball, was a co-captain during her senior season, and was a member of the NAACP Georgetown University Chapter.
