1926 Tom Tryon - Actor (Texas John Slaughter, The Cardinal, In Harm's Way, The Longest Day) and author (Harvest Home, The Wings of the Morning, Crowned Heads, All That Glitters, The Night of the Moonbow, In the Fire of Spring)

I've read only one book of his, Harvest Home. If I remember right, it was very pleasant, almost boring until the end. It was creepy.

1970 Diana Ross and the Supremes performed their last concert together, at the Frontier Hotel in Las Vegas
1982 Clifford Robert Olson was sentenced to life in prison after he pleaded guilty in Vancouver to 11 counts of first-degree murder. The victims, three boys and eight girls, were aged between nine and 18 and died between November, 1980 and August, 1981. It was one of the worst crimes in Canadian history. Olson demanded 100-thousand dollars to be paid to his family by the RCMP in exchange for information on the location of the victims. The agreement caused outrage, especially from the families of the victims. Olson died in prison in September 2011

I would have been outraged as well.
