Maurice P. Kneifl, 58, of Sioux City, Iowa, was last seen on February 14, 1983. He left his girlfriend’s home about 9:30 p.m. in a dark brown 1981 Cadillac Fleetwood and never returned. When he did not pick her up for work the next morning as planned, he was reported missing two days later by the girlfriend and her daughter.

Kneifl was a respected local businessman and a former mayor of Hartington, Nebraska, who at the time owned a dry cleaning business. He had been preparing to testify against his son-in-law, Delbert Beauchene, who had a criminal history; Kneifl thought his testimony could keep Beauchene in prison for a long time. Kneifl and his Cadillac have never been found, and authorities suspect he may have been taken against his will.

Does anyone in the Sioux City or Hartington area remember seeing that dark brown 1981 Cadillac Fleetwood in mid-February 1983 or have information about Maurice Kneifl’s disappearance?
