The Old Montana Prison in Deer Lodge is considered haunted due to its violent history, including the 1959 riots where inmates murdered the deputy warden and held the warden hostage, leading to the murder-suicide of the riot leaders in the northwest tower. Reports from visitors include unexplained footsteps, active cat toys in empty rooms, and perceived conversations with spirits, all contributing to the prison's reputation as a site of supernatural activity. A major riot in 1959 resulted in the murder of the deputy warden and the suicide of the riot instigators, Lee Smart and Jerry Myles, in a prison tower. Several inmates were executed, including George Rock and William Hayes, who killed Deputy John Robinson and wounded Warden Frank Connolly in an escape attempt. The prison was known for being overcrowded and poorly managed, which contributed to the volatile environment. Guests report hearing footsteps in empty areas. A cat toy has been observed lighting up on its own in the absence of any person. Visitors have claimed to have full conversations with spirits within the facility. The Old Prison Museum offers public ghost tours, including entry into areas not normally open, like the Death Tower and Upper Tier Cells. These tours provide guests with paranormal investigation equipment, along with video footage, audio recordings, and photographs taken during their visit.
