DENVER, Iowa — Police say one person has died in a northeast Iowa construction site accident.

The Denver Police Department says construction workers were digging along the foundation wall of a building in Denver when a portion of the wall tipped over on Monday and trapped 56-year-old Henry Gray, of Clarksville.

Firefighters and the owner of Snelling Construction freed Gray from under the wall, but he died at the scene.

The Iowa State Medical Examiner will conduct an autopsy on his body.

Iowa Occupational Safety and Health officials are investigating the incident.

Denver is about 13 miles north of Waterloo and has a population of about 1,800.
