Donald Preston was 51 when he was last seen by family in Fort Dodge, Iowa, on December 22, 2016. He had not been reported missing, but on December 26 his body was found in a field in Moorland, southwest of Fort Dodge. An autopsy confirmed Preston had been shot to death; the case was ruled a homicide.

The Webster County Sheriff’s Office and the Iowa Division of Criminal Investigation handled the investigation. Family members described Preston as outgoing and funny, and his nieces remembered him as a caring uncle. A person of interest was identified early in the inquiry, and investigators later reported that Preston was last seen alive with that man in a car on December 20, 2016; evidence including matched shell casings was said to link a .40 Glock to the killing.

Who in the community might have information about Donald’s movements in the days before Christmas 2016?
