Winona Nona Souix Longee, 35, was one of three people found shot to death inside a Poplar, Montana, residence on the Fort Peck Reservation in September 2025. Reports give two dates: an obituary lists September 14, 2025, while federal prosecutors say the homicides occurred on September 11, 2025. The other victims were 65-year-old Earlene Jones and 41-year-old Matthew Black Thunder; all three suffered gunshot wounds reportedly fired at close range.

According to authorities, the case unfolded after a man called and confessed to killing three people in Poplar and then told deputies he had been using methamphetamine with the victims, became paranoid and believed they were conspiring against him, and shot them with a 9mm pistol. The investigation involved Fort Peck Tribal Police, the FBI, and Roosevelt and Yellowstone county sheriff’s offices. Federal authorities identified and arrested 73-year-old Michael J. Ackerman, also known as Michael J. Littlebull, and charged him in a criminal complaint with three counts of second-degree murder.

Winona Longee was a mother of four boys and was remembered by family and friends ahead of her services. Does anyone in the community have information about Winona, the other victims, or events in Poplar that week?
