The authorities in Oregon said Monday that they had located the remains of the actor Charles Levin, best known for his one-off portrayal of a mohel in “Seinfeld” and a recurring role in the series “Alice” in the 1980s .

Mr. Levin, 70, was found on Saturday several hundred feet from his car, which contained the remains of his pug, Boo Bear , in an “incredibly remote” area near Grants Pass in southwestern Oregon, said Warren Hensman, the city’s public safety chief.

The case is not being treated as a homicide or suicide, he said.

The car was off an “almost impassable road” and had been “disabled due to terrain,” the Grants Pass Department of Public Safety said in a statement.

The actor, who had lived in Grants Pass, had not been heard from since June 28, said his son, Jesse Levin, adding that his father’s last phone call was to a family friend in the area. “It was breaking up,” he said. “It wasn’t very clear what he was saying, but he did seem to sound confused and lost.”
