One person was shot and killed during an apparent home invasion attempt in Koochiching County on Saturday morning.

The Koochiching County Sheriff's Office reported that deputies were called to the 5700 block of U.S. Highway 53 near Ray just before 6 a.m. Saturday.

A preliminary investigation indicated that a male suspect, whose name has not yet been released, had gone to the home asking for help. When the door was opened, officials said, the suspect assaulted the female homeowner.

The homeowner's son intervened and shot the suspect, officials said. The suspect was transported to the Rainy Lake Medical Center in International Falls, where he died from his injuries.

The investigation is ongoing, the sheriff's office reported. Local authorities are being assisted by the Minnesota Bureau of Criminal Apprehension. More details will be released after an autopsy and positive identification is made.
