The Los Angeles County Sheriff's Department said deputies were serving a search warrant for a barricaded arson suspect when the shooting occurred.

A woman suspected of trying to set a neighbor’s home on fire was carrying a large knife when at least one deputy fatally shot her while deputies served a search warrant at her Rosemead home early Thursday morning, Feb. 27, an investigator said.

The female suspect wanted for an arson situation was struck by police gunfire. She was taken to an area hospital where she was declared dead by medical personnel.
