A University of Michigan graduate student disappeared after a mysterious plane crash in Canada last week -- with no sign of a body or footprints at the scene, according to local reports.
The plane, found on autopilot and out of gas, was discovered in northern Ontario, about 400 miles from Harbor Springs, Michigan, the flight’s planned destination.
Nothing surrounding the wreckage suggested anyone was near the plane at the time of the crash, Thunder Bay News reported, adding that there weren't even any tracks in the snow.
Ontario Provincial Police said they completed a subsequent search of the area for the student, but it was unsuccessful.
The unnamed student was last seen on March 15, the same day he rented the plane, the Detroit Free Press reports.
Police say that the single-engine Cessna 172 was rented out of Ann Arbor and was registered to University of Michigan Flyers Inc.
The Transportation Safety Board of Canada and University of Michigan police are continuing to investigate the plane crash and the student has been filed as a missing person.
