The Loudoun County Sheriff’s Department in Virginia was called to the Costco because the worker was acting strange.
A woman who witnesses said was handing out pizza samples at a Costco in Sterling, Va., was shot and killed by sheriff's deputies Wednesday after allegedly threatening them with a knife.
Witnesses said the suspect, a contracted employee who was handing out pizza, was acting "strangely" and authorities were called.
Loudoun County Sheriff Michael Chapman told reporters that the woman was holding a knife when officers approached her. She did not respond to orders to drop the weapon and then she charged the officers.
