On Friday, an emergency cell phone made authorities search in a remote area northeast of Selma, the Grants Pass Public Safety Department said. But there was no trace of Levin.
A resident found Levin's car on Saturday on a remote, almost impassable road. The disabled vehicle was off the road, police said.
Levin's pug, Boo Bear, was found in the vehicle. Levin's body was located near the car, police said.
"Based on the circumstances, there is a high probability that the remains are those of Charles Levin," police said.
The medical examiner will make the final identification of the remains, said the police.
Levin also had roles in movies, such as "The Golden Boy."
