UPDATE: Medical Examiner releases report on fatal industrial accident

MILWAUKEE (WITI) --The Milwaukee County Medical Examiner's Office has released its report on an incident in which a 38-year-old Greenfield man was killed in an industrial accident on Milwaukee’s south side early Thursday morning, May 22nd.

38-year-old Stephen Rauth, who works for Nuvo Construction, was killed while making a repair in a concrete mixing tower at Songa Ready Mix. 

The Milwaukee Fire Department tells FOX6 News Rauth was on a conveyor that feeds a hopper — and was crushed.

According to the Medical Examiner's report, video evidence of the scene showed Rauth arriving at the machine around 12:21 a.m. He could be seen walking around the cat-walk and appeared to begin work at 12:26 a.m.

After authorities investigated the scene and spoke with employees, it was determined that Rauth was most likely standing on a full hopper, adjacent to the malfunctioning bin, when the incident occurred.

According to the report, there was a "turn head" or chute that rotated on-demand when a hopper got low on product. This only rotated clockwise, and likely moved to fill the sand hopper -- ultimately trapping Rauth against the malfuncting bin rail and the large "turn head" machine.

Rauth was unable to survive his injuries.

As is standard practice in industrial accidents, OSHA has been notified.

Amanda Lee tells FOX6 News it was her older brother who was killed.

“We woke up to my mom screaming. My sister-in-law called my mom, and my fiance and I were sleeping,” Lee said.

OSHA’s investigation into this incident could take up to six months to complete.

OSHA tells FOX6 News Nuvo Construction has no history of OSHA violations.
