He had a younger sister named Holly.

He appeared with his father in the 1966 episode "The Cave-In" of the series The F.B.I.. McIntire long struggled with alcohol and other drug problems, which combined with his heavy build in his later years contributed to his death at the age of forty-one from congestive heart failure in Los Angeles.
