A girl was found dead in a small northern Minnesota community, and authorities said Wednesday that they are treating her death as a crime.

The Cass County Sheriff’s Office said it was notified shortly after 8 a.m. Friday of the body being discovered in Cass Lake, a town of about 750 people located within the boundaries of the Leech Lake Indian Reservation.

Autopsy results are pending, but the Sheriff’s Office ruled out suicide as a cause.

The Sheriff’s Office has declined to release the girl’s name, her age, specifics about where her body was found and why her death is being investigated as a crime.

The state Bureau of Criminal Apprehension and tribal police are assisting with the investigation.
