Authorities in southern California on Monday are searching a campsite for clues after a scientist was fatally shot inside a tent with his two young daughters.

Tristan Beaudette, 35, of Irvine, Calif., was bleeding from a chest wound when deputies found him in a tent early Friday at a Malibu Creek State Park campsite.

Authorities said Beaudette was shot at least once in the upper torso, The Los Angeles Times reported.

His daughters, ages 2 and 4, were unharmed in the shooting that reportedly occurred about 4:45 a.m.

Beaudette took the girls camping so his wife, a doctor, could study for an exam, according to reports. He worked as a scientist for a pharmaceutical company and he and his wife were about to move to the Bay Area.

Deputies said they had no leads, no suspect and no motive, KCBS Los Angeles reported.

His family remembered him as a devoted father who “found true joy” in his life with his children.

“The grief and trauma this loss has caused our close-knit family is indescribable,” the family’s statement read.

The park had been the backdrop for the TV series “M.A.S.H.,” as well as “Butch Cassidy and the Sundance Kid” and the original “Planet of the Apes” film, according to the paper.
