Celebrities who died young: Remembering Jon-Erik Hexum
Nice video of Celebrities that died young. Some I had forgotten about.
Included is Jon-Erik Hexum: (November 5, 1957 – October 18, 1984)
Hexum allegedly turned down plenty of opportunities to appear in shows such as "The Dukes of Hazzard" (1979) & "CHiPs" (1977) and many day time soap operas before finally making his debut in the TV series "Voyagers!" (1982) as time traveler Phineas Bogg. He was then cast as hunk Tyler Burnett alongside Joan Collins in Making of a Male Model (1983) (TV), and then as ex-Green Beret, Mac Harper in the TV series Cover Up (1984) (TV).
However, on October 12th, 1984 after a long and draining day's shooting on the set of Cover Up (1984) (TV), Hexum became bored with the extensive delays and jokingly put a prop .44 magnum revolver to his temple and pulled the trigger. The gun fired, and the wadding from the blank cartridge shattered his skull, whereupon the mortally injured Hexum was rushed via ambulance to hospital to undergo extensive surgery. Despite five hours of work, the chief surgeon Dr David Ditsworth, described the damage to Hexum's brain as life ending, and one week later on October 18th, he was taken off life support and pronounced dead. However, Hexum's commitment to organ donation, meant five other lives were assisted or saved with organs harvested from him. The youthful & charming Hexum was dead at only 26 years of age.
