Authorities Monday released more details about a deadly shooting of a man inside a beauty supply store in Compton, saying the man threatened people before being gunned down.

The investigation initially began Sunday afternoon when a man, who allegedly caused “some destruction” inside Pink Beauty Supply on Alondra Boulevard near Long Beach Boulevard, was shot and killed, according to the LA County Sheriff’s Department. Investigators said another customer inside the store fired her weapon, fatally striking the man. 

Investigators now believe the man, 43, walked into the store and sexually assaulted a female customer by grabbing her chest. The man then began throwing items at the staff while making threats and claiming he could kill everybody, the sheriff’s department said.

As people inside the store feared for their safety, another female customer in her 50s took out a weapon and opened fire. All store employees corroborated the story, the sheriff’s department said. 

Investigators do not believe there’s criminal culpability at this time, the sheriff’s department added. 

The LA County District Attorney’s office will decide whether the woman needs to face charges.
