Donald Charles Shumaker was 41 when he was last seen on December 8, 2013, near North 12th Street and East Indian School Road in Phoenix, Arizona. Few specifics about that day have been released publicly: reports do not describe what he was wearing or his state of mind, and no clear leads have been made public since his disappearance.

The investigation remains open and the lack of detail has complicated search efforts and the family’s ability to find answers.

If anyone saw Donald around North 12th Street and East Indian School Road on or just after December 8, 2013, or has information that could help locate him, please come forward to the authorities handling the case.
