The TV star, who was 71 at the time of his death, was killed on June 12 2023, after Mr Koss' Honda Element SUV turned into the path of his motorcycle. Following the collision on Route 30 in Dorset, Vermont, Treat was airlifted by helicopter to Albany Medical Center in Albany, New York, where he was pronounced dead. 

News of his passing was first confirmed by the actor's publicist of 15 years, Barry McPherson, who said in a statement: "He was killed this afternoon. He was making a left or a right [turn, and] a car cut him off."

Treat is survived by his wife of 35 years, actress Pam Van Sant, and their two children, son Gill, 31, and daughter Elinor, 25. In the statement confirming his death, his publicist added: "I'm just devastated. He was the nicest guy. He was so talented.
