INDIANAPOLIS, Ind. (June 16, 2014)—The official cause of death of a Citizen Energy contractor last Friday was determined to be accidental, said the Marion County Coroner’s Office.

William Isaac Simpson, 25, was working at the Deep Rock Tunnel Connector Project near West and Raymond streets when he was killed. Officials said Simpson was 250 feet below the ground and in the tunnel system.

An autopsy revealed Simpson died from a crushing blunt force traumatic injury of the head.

At this time, it is unclear what caused the incident, but Citizens Energy confirmed it was not caused by a structural compromise or collapse.

The Deep Rock Tunnel Connector Project is a massive tunnel that’s going to act as a temporary storage area for billions of gallons of raw sewage. Right now, the sewage flows into waterways in Indianapolis.

The eight-mile tunnel system will store 250 million gallons of raw sewage when it is finished, scheduled to occur in 2016. The entire project will take more than 10 years to complete and will cost an estimated $1.4 billion.

I-OSHA is investigating the incident and it could take two or three months.
