Bodycam shows woman armed with knife slashing Virginia police officer before being shot

Newly released bodycam footage shows a Virginia police officer fatally shooting a woman with a knife who slashed the officer during a wellness check last month.

Fairfax County police released the footage following uproar over the death of the woman, 33-year-old Sydney Wilson. The footage shows crisis intervention officer Peter Liu approaching Wilson's apartment after her doctor raised concerns about her mental health.

Liu knocks on the door and Wilson answers first before quickly closing the door again. The officer then continued knocking on the door for almost ten minutes.

The footage shows Wilson suddenly opening the door and immediately attacking Liu with a knife. The officer quickly backed into the hallway, drew his firearm and ordered Wilson to back away.

Wilson is seen chasing Liu with his knife raised as Liu retreats further into a dead-end hallway. He repeatedly gave Wilson verbal instructions to “back up,” and she stops briefly as he raises his gun, but then continues toward him.

Liu retreats until his back is against another apartment door, all the while issuing the “please go back” commands. Wilson continues to approach him with the knife raised and then strikes him again.

Liu fires his gun as Wilson continues to attack him with the knife. He pushes past her into the open hallway, but Wilson grabs him and continues to attack him with the knife, causing Liu to fire more shots.

The officer then retreats into a longer hallway as Wilson collapses.

Footage from two officers who responded shortly after the incident shows Liu's face covered in blood from where Wilson slashed his forehead. One of the officers attempted to revive Wilson but was unsuccessful.

“Our police officer acted bravely. He certainly showed some grace under pressure,” Fairfax County Police Chief Kevin Davis said in a news conference Monday.

However, Davis confirmed that Liu is on administrative leave pending a criminal and internal investigation.
