Body-cam footage shows Fairfax officer shooting woman with knife in hallway

A Fairfax County police officer fired five shots at a woman who appeared to slash his face with a knife in a Reston apartment building last month, fatally wounding her, according to newly released body-camera footage showing a roughly four-minute interaction that began when the officer was called to conduct a welfare check.

Fairfax Police Chief Kevin Davis at a news conference Monday stood by the actions of his officer, who the department identified as Peter Liu, a 14-year veteran.
