MURRAY, Iowa (AP) — Authorities say a farm worker has died after entering a grain bin in southern Iowa. Clarke County Sheriff Bill Kerns says the worker entered the bin Wednesday morning as he and a farm owner were trying to break up a crust that had formed on soybeans inside. The farm owner checked on the man about 10 minutes later and couldn’t see him.

Crews from at least five four departments responded to the bin near Murray, and Kerns says rescuers cut a number of holes into the structure to extract grain while they tried to reach the man.

They were able to retrieve the man’s body about noon. The man, whose name wasn’t released, was from Creston.
