In the course of one day, police in Utah were called to two bombings. Businessman and Mormon bishop Steve Christensen was killed by bomb left in front of his office door. Kathy Sheets, wife of Gary Sheets, who was Christensen's former business partner, was killed by a similar bomb left on the doorstep of their residence. Police had difficulty determining the motive for the killings until a third bomb went off, injuring Mark Hofmann. After careful analysis, it was determined that Hofmann was actually the bomber and that the bomb had gone off accidentally while he was moving it into his car. The motive for the killings was a mixture of fraudulent historical documents and not having enough time to create promised documents.
