SAC COUNTY, Iowa – The Iowa Office of the State Medical Examiner conducted a forensic autopsy on the body discovered in Sac County on April 24, 2024. The body has been positively identified through dental records as that of 53-year-old David Schultz of Wall Lake, Iowa.

Schultz was located in a farm field in the 1900 block of Union Ave. in Sac County. Preliminary autopsy results show no signs of trauma or serious injury. Further autopsy test results are pending. Authorities do not suspect foul play in the death of Schultz, who was first reported missing by his wife on Nov. 21, 2023.

Schultz left his Wall Lake home around 7 p.m. on Nov. 20. He went to pick up a load of pigs from a hog confinement in the Eagle Grove area. He left around 10:5o p.m. Video footage shows Shultz at a truck stop around 11:15 p.m. on Nov. 20. After leaving the truck stop, his semi-truck was seen heading west on Iowa Department of Transportation cameras.

Cell phone data shows Schultz’s phone traveling to the location where the semi-truck was found — the intersection of D-15 and N-14. Data suggests the semi-truck may have been there since 12:40 a.m. on Nov. 21. The morning of Nov. 21, Schultz didn’t drop off his load of pigs at the Wieckman hog buying station in Sac City. Sarah Schultz, David Schultz’s wife, reported him missing that afternoon after learning he did not show up to Wieckman’s.

A Sac County Secondary Road employee reported that a semi-truck had been at the intersection of D-15 and N-14 since early morning. Responding deputies determined the semi-truck to be Schultz’s. His phone and wallet were found inside. His semi-truck, with a load of pigs, was found at an intersection near Sac City with his wallet and cell phone inside.

The United Cajun Navy, a search and rescue group based in Louisiana, organized a volunteer search. Almost 200 volunteers participated in the initial search that covered more than 100,000 acres.
