Two dead, one seriously injured in Plains shooting; suspect in custody

Authorities said there was no ongoing threat to the community. That is the immediate public-safety reassurance, but it is not yet an explanation of the shooting: investigators have not publicly established in the available account what led to the gunfire or what role the person in custody allegedly played.⁠1

Police received the disturbance and shots-fired report Saturday around 11:27 p.m. Officers then went to the Prairie Lane residence and found the three victims. The reported time belongs to the call to police; it does not establish exactly when the shooting happened. NBC Montana’s account, published November 1, 2026, identifies the night as Saturday without explicitly giving an incident calendar date.⁠1

The sequence matters because the response and the detention happened in different towns. The victims were found at the Plains home, in Sanders County. The suspect was taken into custody in Hot Springs after the police chief there located a vehicle described as a possible suspect vehicle.⁠1

According to the sheriff’s office information reproduced by NBC Montana, information about that vehicle reached law enforcement after the initial response. It reportedly had left the scene before officers arrived. The Hot Springs chief subsequently located it and took a suspect into custody without further incident.⁠1

The account provides no arrest time, so it does not establish how long the interval was between the report from Prairie Lane and the detention in Hot Springs. Nor does the description of a possible suspect vehicle establish who drove it, whether anyone else was inside, or that there was a police pursuit. Those details should not be filled in from the fact of the arrest.⁠1

There is also a limited identification discrepancy concerning the arresting chief. NBC Montana’s November 1 report names the chief as Larsen; the town of Hot Springs’ law-enforcement directory lists Police Chief Eric Larson. The spelling difference remains unresolved. It does not amount to a competing account of the casualty count or the town where the suspect was detained.⁠1⁠17

The available incident account does not identify the two people who died, the injured person or the suspect. It also does not establish relationships among them, a motive or formal criminal charges. A person being taken into custody is not a finding of guilt, and the reported detention alone cannot explain what happened inside the house.⁠1

The survivor’s condition remains another important unanswered point. “Serious gunshot injuries” describes what officers encountered when they arrived. No subsequent medical update is established in the available reporting, so that description should not be read as a verified assessment of the person’s later condition or prospects for recovery.⁠1

Local coverage is consistent on the central outcome. KPAX and the Missoulian also reported two deaths and a suspect in custody, attributing the incident information to the sheriff’s office. That agreement reinforces what authorities reported, but it is not independent eyewitness confirmation of how the shooting unfolded.⁠11⁠2

The next substantive update would need to go beyond the custody announcement: identification of those involved, a verified condition update for the survivor, any charges and an account of the circumstances. For now, the sheriff’s office says the investigation continues. The immediate threat assessment has been given; the explanation for two deaths and a third person’s injuries has not.⁠1
