CASTAIC, Calif. (AP) — A 67-year-old man found alive days after his car plunged 200 feet off a mountain road built a makeshift camp, ate leaves and drank water from a nearby creek to survive, his daughter said.

Family members found David Lavau at the bottom of a ravine off Lake Hughes Road in the Angeles National Forest Thursday after conducting their own search, said Los Angeles County Fire Department Capt. Mark Savage.

Another vehicle was found nearby, but its driver did not survive the crash and there were no details on how the cars ended up off the road, said Savage.

David Lavau’s daughter, Lisa Lavau, told KCAL-TV her family had not heard from her father for several days and reported him missing to police.

Authorities told Lisa Lavau that her father had used his debit card at a nearby grocery store, so she decided to conduct a search of the area along with her daughter and brother.

“We stopped at every ravine, and looked over every hill and then my brother got out of the car and we kept screaming and the next thing we heard Dad saying ‘help, help,’ and there he was,” Lisa Lavau said.
