A 2-year-old boy died and three family members were injured in a house fire in northwestern Minnesota.

The Becker County Sheriff's Office got a 911 call shortly before 1 a.m. Sunday about the fire northeast of Detroit Lakes.

The first deputy on the scene found the house fully engulfed.

Children in the basement heard smoke alarms, saw flames on the main floor and alerted family members, who escaped. After learning a 2-year-old was missing, his father and an older brother went back in but couldn't find the boy. Micah Hedlund was later found dead.

The father, 48-year-old Michael Hedlund, was airlifted to a Fargo hospital for smoke inhalation. The mother, 46-year-old Melissa Hedlund, and a 5-year-old girl were airlifted to Minneapolis for smoke inhalation and burns.

The State Fire Marshal's Office is assisting in the investigation.
