DUNLAP, Iowa (AP) — Officials pulled a man’s body from a western Iowa sand pit hours after the dump truck he was driving fell into water in the pit.

Authorities and rescue workers were called Thursday morning to Hallett Materials in Harrison County just south of Dunlap for reports of a missing truck and driver. Sometime later, crews discovered the truck submerged in the sand pit under ice and water.

The driver was trapped inside the truck, where he died. His body was recovered Thursday afternoon.

Officials have not yet released the man’s name. Officials are conducting an investigation into what caused the accident. .
