On November 6, 2021, in Bainville, Montana, Jennifer Mann, a 49-year-old White/Caucasian woman, was killed inside the Stateline Casino during a domestic violence incident that also claimed two other lives. Deputies who responded found three people dead at the scene. Surveillance footage, described by the Roosevelt County sheriff, showed Jennifer's husband, 56-year-old Bradford Mann of Williston, North Dakota, shooting Jennifer and 63-year-old Scot Panasuk of Bainville before turning the gun on himself. Authorities said all three knew one another and that no one else was injured.
The shooting unfolded in the early evening, prompting an immediate law enforcement presence at the casino on the Montana–North Dakota border. Local and regional outlets reported the sequence of events as a double murder–suicide borne out on security video, with investigators recovering evidence that supported that account.
With the suspected shooter deceased at the scene, there were no arrests; the case was handled as a murder–suicide rather than an open homicide investigation.
Public memorial listings and tributes later recorded Jennifer's death in Bainville on that date, noting her age and confirming the location, while community pages dedicated to gun-violence victims also reflected the sheriff's account of what happened. These records, together with contemporaneous news reports, present a consistent picture: Jennifer Mann's life ended in an act of domestic violence that left two victims and the perpetrator dead in a small-town casino near the state line.
