Summary based on the NamUs case record (MP338) and 11 other sources
Marvin Duane Witte, aged 51, was last seen on December 12, 2005, in Winona, Minnesota, after leaving the Hiawatha Valley Mental Health Center around 2:30 p.m. He never returned home, and his whereabouts remain a mystery. Witte had a history of medical issues, including asthma, depression, anxiety, and panic attacks, for which he required multiple medications. His apartment was found in a concerning state on December 22, with the television still on, his pet cat unattended, and his car and motorcycle still parked outside.

Witte's disappearance raised immediate concerns, particularly as he missed a doctor's appointment on December 18, something he was known to do on occasion. However, his failure to contact family during the Christmas holidays was uncharacteristic, prompting further alarm. Authorities initially suspected suicide, as one of his prescriptions was missing, and Witte had previously mentioned that if he ever took his own life, it would be in a river. Despite extensive searches in the Mississippi River, Lake Winona, and surrounding wooded areas, no evidence was found.

While no definitive answers have surfaced, Witte's family held a memorial service for him in March 2006. His case remains open and unsolved, with the Winona Police Department continuing to investigate.
