WOODBRIDGE, Va. (AP) — A newly sworn-in police officer on her first shift with her Virginia department was shot and killed Saturday and two of her colleagues were wounded in a confrontation stemming from a call about an argument.

Officers received a call around 5:30 Saturday evening in Woodbridge, just outside Alexandria, about a “verbal argument,” Sgt. Jonathan Perok, spokesman of the Prince William County Police Department, said. It’s not clear how the altercation between the suspect and the police began the suspect is in custody and was not injured, he said.

The department announced on its Facebook page that Officer Ashley Guindon had died, “as a result of her injuries sustained during the incident.”

Guindon had been a county police officer a few years ago and had left and returned to the force, Corey Stewart, chairman of the Prince William County Board of Supervisors, said in a phone interview with The Associated Press on Saturday night. He did not know the exact dates of when she started and left, he said.

A picture of Guindon was posted to the department’s Twitter page on Friday with a tweet that read, “Welcome Officers Steven Kendall & Ashley Guindon who were sworn in today & begin their shifts this weekend. Be Safe!”

It is not known if the other officer in the tweet was involved in the shooting incident.

The Facebook statement said the remaining two officers wounded during the encounter are continuing to be treated for their injuries. They were not identified in the statement.

Police said the incident is still being investigated.
