Matthew Robert Long, 35, died on May 5, 2021, in Corvallis, Montana, after a prolonged standoff with law enforcement. Concern for his well-being prompted the Ravalli County Sheriff’s Office to respond on May 3, when deputies found Long barricaded inside a rural residence and reported he was in possession of firearms. Initial attempts at communication failed and nearby residents were evacuated as officers, including a specialized team, secured the scene.

The standoff lasted nearly two days and ended on the morning of May 5, when Long was confirmed dead. No other people were reported harmed. The Ravalli County Sheriff’s Office conducted the investigation. An obituary from Long’s family described the incident as a horrific experience, thanked the Sheriff’s Department for their response, and referenced struggles with the mental healthcare system that the family said they intended to address.
