INTERNATIONAL FALLS (AP) - A northern Minnesota man is dead after authorities say he refused to leave a burning convenience store that he was accused of illegally entering.

The Koochiching County Sheriff's Office says authorities responded to a report of a break-in late Wednesday at the Y Knot Quick Stop gas station at Pelland Junction, southwest of International Falls. Authorities say 26-year-old Colton Tammi was inside, and allegedly told dispatchers that he would shoot responding officers.

Authorities say the store began burning after deputies surrounded it.

Sheriff Perryn Hedlund says firefighters could not enter due to the threat of gunfire.

The fire was put out and Tammi's body was found inside. His cause of death and the cause of the fire are being investigated.

Hedlund says there are many unanswered questions.
