Friar Ted
If you are referring to Sergeant Carter of Gomer Pyle USMC, that was Frank Sutton and he died of a heart attack.
Of course, Bud Dwyer did it live during a press conference which probably helped a bit.
Live video of the suicide (definitely not for the squeamish…)
Yukio Mishima
Perhaps even more shocking, was the on air suicide of newscaster Christine Chubuck.
(It’s a Wikipedia article. No graphics or videos of the suicide).
Sad.
Actually, Kurt Cobain didn’t committ suicide , he was murdered by his wife Courtney Love and a man named Mike Dewitt.
