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. It was the deadliest explosion of any type in the history of the Las Vegas Valley.
After the bombing, the Nevada State Legislature attempted to pass the Orbit Inn Act, which would have restricted the possession or sale of high explosives for individuals who did not have authorization to handle such material. Facing opposition from the mining industry, the bill did not pass in the legislature.
