Police say the man killed in an industrial accident in Superior Tuesday night got caught in a conveyor belt system.

The Superior Telegram reports emergency crews were called to White Cedar Shingles and Lumber Company, a wood shingle manufacturer, in northwest Superior just after 7 p.m.

David M. Clink, 30, of Superior, who had been working alone, was found unresponsive. Police say the preliminary investigation indicates Clink's arm or clothing got caught in a conveyor belt, pinning Clink against the machinery and causing him to asphyxiate.

The man was found by a co-worker who notified police.

The Occupational Safety and Health Administration arrived at the scene late Wednesday morning to conduct an investigation.
