(LUDINGTON, MI.) - The names of a Northeast Indiana couple who died following a plane crash in Northern Michigan have been confirmed.

Michigan State Police from the Hart Post say 60 year old Randy Strebig and 43 year old Allison Wheaton, both of Lake James, died along side their two dogs on Sunday at 10 AM as a result of a plane crash in Ludington, Michigan. The couple were reportedly visiting family.

Strebig and Wheaton were departing from the Mason County Airport when for an undetermined reason their Socata TBM-700 plane went down and caught fire. The Pere Marquette Township Fire Department’s Facebook page said the plane crashed outside the airport fence, located on Meyers Road off of Rasmussen Road.

The fire department noted the plane was not easy to reach and they needed off-road vehicles in order to reach the accident.

The cause of the crash remains under investigation.

The Federal Aviation Administration has been investigating the crash since Sunday with help from the National Transportation Safety Board.
