The Marion County Coroner said Monday that 25-year-old Isaac Simpson died from a crushing blow to the head.
Isaac was working 25 feet below ground Friday when he died. Officials said Simpson was working as a laborer for SK-JV, a joint venture that has contractors working for Citizens Energy Group. He was on an 11 p.m. to 7 a.m. shift when he died.
Citizens and the Indiana Occupational Safety and Health Administration were still investigating how the accident happened.
Citizens workers were constructing an eight-mile-long tunnel that will eventually help keep up to 250 gallons of raw sewage from entering area waterways.
A Citizens spokeswoman released the following statement Monday afternoon:
While the Deep Rock Tunnel job site has been cleared to reopen, out of respect for the family of William Isaac Simpson and the friends who worked alongside him, SK-JV, in consultation with Citizens Energy Group, has decided to keep the site closed for the present.
