BELMOND, Iowa (AP) – Authorities are investigating the death of a northern Iowa co-op worker whose body was found in a semitrailer loaded with grain. Belmond police say 57-year-old Daniel Feller was pronounced dead Monday at the MaxYield Cooperative facility. A co-op statement said Feller had fallen from a platform while grain was being loaded into the semitrailer. The co-op says Feller had been an employee for more than 10 years.

MaxYield also said safety regulators completed an investigation Tuesday.
