UPDATE: Radar reports Levin's son thinks his father's death was "a tragic accident," and does not suspect foul play.
Charles Levin, the 70-year-old actor remembered as the nervous mohel on the 1993 Seinfeld episode "The Bris", is thought to have been found dead in Grants Pass, Oregon, KOBI5 reports.
Investigators searching for the missing actor — who according to his son vanished Monday while in the process of moving — discovered what are believed to be his remains after a local resident found Levin's orange Fiat on an "almost impassable" road.
Inside the car was the body of his beloved dog Boo Boo Bear.
While not a well-known name, Levin had a highly recognizable face, and along with his Seinfeld role gave several impactful performances in his 20-plus-year career in Hollywood.
Debuting in 1976, he went on to appear in small roles in the Woody Allen films Annie Hall (1977) and Manhattan (1979); appeared in the well-received movies The Seduction of Joe Tynan (1979), Honeysuckle Rose (1980) and This Is Spinal Tap (1984); played the groundbreaking part of a sympathetic gay hustler on Hill Street Blues (1982-1986); had a recurring role on Alice (1983-1985); and was gay housekeeper Coco on the pilot of The Golden Girls (1985), a character who was dropped from the series.
Levin made many other appearances on episodic TV on top-rated series, and ended his acting career with the 1998 film A Civil Action.
Presuming the remains are confirmed to be his, he is thought to be survived by three children from his two marriages.
