Hi-Fi murders

The Hi-Fi murders were the torture of five people resulting in three deaths during a robbery at the Hi-Fi Shop, a home audio store in Ogden, Utah, United States, on the evening of April 22, 1974. Several men entered the Hi-Fi Shop shortly before closing time and began taking hostages. They forced their victims to drink corrosive drain cleaner, which the perpetrators believed would fatally poison their hostages, but instead caused burns to their mouths and throats. Further violence included kicking a pen into an ear and the brutal rape of an eighteen-year-old woman, before three of the victims were fatally shot. The two surviving victims were left with life-changing injuries.
