First responders were dispatched Friday morning to the plant and found the man caught in a large roll-up industrial door, Vigo County Sheriff John Plasse said.

Fire department personnel could not find a pulse on the victim while he was still caught in the door, and once he was released, they determined he was dead. An initial investigation indicates the man was possibly repairing or working on the door when he became caught in it, the sheriff said.

The investigation is ongoing pending an autopsy, Plasse said. The man’s name was not immediately released.
