Orbit Inn bombing
On January 7, 1967, 28 year-old Richard James Paris detonated 50 sticks of dynamite at the Orbit Inn Motel in Las Vegas, Nevada, killing himself, his 22-year-old wife Christine, and four other people, as well as injuring 8 other people. Paris was allegedly angered at his wife over having an affair and detonated the dynamite by shooting it with a gun once she arrived back at the motel room.
