Tristan Beaudette, who was shot in front of his two young daughters while on a camping trip, died from a gunshot to the head, PEOPLE confirms

The California father shot in front of his two young daughters while on a camping trip died from a gunshot to the head, PEOPLE confirms.

Assistant Chief Ed Winter of the Los Angeles County coroner’s office tells PEOPLE Tristan Beaudette passed away from a single shot to the head.

Beaudette, who was a 35-year-old scientist, had taken his daughters, ages 2 and 4, camping overnight with him in California’s popular Malibu Creek State Park outside of L.A. so his wife, Erica, could study for an exam at home.

“I don’t believe there was multiple gunshots,” says Winter. Beaudette was pronounced dead at 5:21 a.m. Winter says his autopsy has not been completed but that a full report would be available once transcribed.

“The Sherriffs are still searching for a suspect and motive,” it continued. “If you or anyone you know might have any information, please contact the LA County Sherriff at 323-890-5500.”
