Mark Duane Folz, 49, was last seen January 16, 2003, in Minneapolis. He was recorded at an ATM near the 1500 block of East Lake Street around 2:00 p.m., and some reports place him at the Minneapolis Veterans Affairs Medical Center that day. Folz planned to drive to Hastings but never arrived. He was driving a burgundy or maroon 1991 Ford Taurus, Minnesota plate DTC-675, which is also missing.

Folz is white, 6 feet 0 inches to 6 feet 1 inch, 225–250 pounds, with brown graying hair, blue eyes, a teardrop tattoo below his right eye, and both legs amputated below the knees; he wore prosthetics. He is diabetic and did not have medication with him. No bank activity has been found. The Willmar Police Department, with the Minnesota Bureau of Criminal Apprehension, continues to list him as an endangered missing person. Anyone with information about Mark or the Taurus is asked to come forward.
