SAC CITY, Iowa—An Iowa truck driver who vanished last fall and whose body was found in a farm field this spring died of hypothermia related to acute methamphetamine intoxication, an autopsy found.
State medical examiner Dr. Kelly Kruse ruled that 53-year-old David Schultz’s death was an accident, the Sioux City Journal reported. Schultz, who was also a farmer, was found dead on April 24 in a Sac County field about a quarter-mile (half a kilometer) from where his semi was found parked in the middle of the road on Nov. 21.
