Although he never won another regular role in a television series, Fontaine made many guest appearances on shows such as 77 Sunset Strip, Baretta, Happy Days, The Rockford Files (as a different character in four episodes) and Quincy.[6]
In 1984, Fontaine was convicted in a murder-for-hire case. According to police documents, in 1983, he approached a country singer with the promise of a recording contract with RCA and a large sum of money if the man were to kill his estranged wife, with whom he was engaged in a custody battle. He was sentenced to four years in a California prison. He had previously been convicted of child molestation and grand larceny. Fontaine successfully appealed his murder-for-hire conviction based on the trial judge's rulings concerning these earlier offenses.[7]
