MOORHEAD, Minn. (AP) — Authorities say the death of a person found after a Moorhead house fire is suspicious.

Crews were called to the fire Tuesday. Responders did not immediately find any victims inside the home, but a search through the rubble uncovered a burned body.

The Ramsey County medical examiner's office will positively identify the body.

The cause and origin of the fire is still under investigation. The Minnesota Bureau of Criminal Apprehension and the state fire marshal are involved in the investigation.
