EVART — Police are searching for a missing Evart man after his vehicle was found in the waters of the Muskegon River Sunday morning.

At approximately 10 a.m. on Nov. 29, troopers from the Mount Pleasant Michigan State Police Post responded to a report of a vehicle in the river near off Trout Haven Drive in Osceola Township just outside of Evart in Osceola County.

Early investigation found that a 2003 GMC Yukon had been driven into the river from the private yard of 60-year-old Donald Garry Tiegen. Troopers were unable to contact the resident and neighbors had not seen him in recent days.

The vehicle was recovered from the river with the assistance of the Michigan State Police Dive Team and a local towing company. The vehicle was unoccupied. It was confirmed that the vehicle belonged to Tiegen.

The last contact he had with family was Saturday by phone. Family members advised law enforcement officials that Tiegen is in poor health and may be disoriented or confused.

Members of the MSP Dive Team have been searching the river while MSP aviation and canine teams search the area. According to MSP Sgt. Kim Vetter on Dec.1, there are no updates on the situation. The canine units have been called off and the dive team is finishing their search in and around the riverbank.

"There's no indication that he's been there," Vetter said. "The investigation is ongoing and nothing is ruled out until we find him."

Individuals with any information about the whereabouts of Tiegen are being asked to call 911.
