Marvin Duane Witte, 51, was last seen in Winona, Minnesota, on December 12, 2005, after leaving the Hiawatha Valley Mental Health Center about 2:30 p.m. He never returned to his apartment and did not contact family during the Christmas holidays, which was noted as out of character. Witte had asthma, depression, anxiety and panic attacks and took multiple medications.

On December 22 his apartment was found with the television still on, his cat unattended, and his car and motorcycle parked outside. One of his prescriptions was missing, and Witte had reportedly said in the past that if he took his own life it would be in a river, leading authorities to search the Mississippi River, Lake Winona and nearby woods without finding evidence. His family held a memorial service in March 2006, and the Winona Police Department continues to investigate.

Did anyone in Winona or the area have contact with Marvin in mid-December 2005 or see him after December 12?
