A 65-year-old Plymouth, Minn., man was killed when the plane he was flying crashed Wednesday near the Moose Lake Carlton County Airport.

The body of Thomas Jay Stillwell was located after his single-engine plane went missing Wednesday night, the Carlton County Sheriff’s Office said in a news release Thursday afternoon.

The Federal Aviation Administration reported an overdue flight at approximately 8 p.m. Wednesday to the Carlton and Pine County dispatch. The flight departed at 4:30 p.m. and was scheduled to land at the Crystal airport at 5:15 p.m. Wednesday.

The Mooney model M20J single-engine airplane was found Thursday partially submerged in the Moose Horn River, a short distance northwest of the end of the Moose Lake Carlton County Airport runway, according to the release.

Stillwell was located after the search for the missing plane resumed early Thursday. An autopsy will be performed for positive identification and to determine the cause of death.

The investigation will continue to determine the cause of the crash. The FAA and National Transportation Safety Board will each be sending investigators, the release said.
