The hunky '80s star and boyfriend of singer E.G. Daily seemed poise to make a major breakthrough with the NBC series "Cover Up," but accidentally took his own life on set. During a lull in filming, Hexum allegedly began playing with a prop gun that had been loaded with blanks. He jokingly put the barrel to his head and then fired. Hexum apparently didn't realize that prop bullets package gun powder in hard substances, and the injuries he sustained from the blanks ultimately left him brain-dead. CBS kept the show on the air for the remainder of the season.
