A Virginia woman was shot and killed this week after threatening police with a knife at a Costco in a Washington D.C.-area suburb.

According to a statement from the Loudoun County Sheriff’s Office, officers responded to a report of a disorderly woman at a Costco in Sterling, Virginia. The woman, later identified as 38-year-old Mhai Scott, was reportedly threatening store employees with a knife and scissors.

Two deputies arrived at the store and attempted to subdue the woman with a Taser. According to the Sheriff’s office statement, the Taser was “ineffective” at stopping the woman. The deputy who was not using the Taser then fired multiple shots at the woman.

The woman died in the Costco and one deputy was taken to a nearby hospital for unnamed injuries sustained during the incident. The deputy is now in good condition.

According to an NBC 4 report, Scott was working at the Costco at the time of her death, handing out pizza samples to customers. Witnesses described Scott as making strange comments about the pizza.
