UPDATE: TOSHA now investigating fatal trench collapse

UPDATE: Tennessee's Occupational Safety and Health Administration (TOSHA) is investigating the deadly trench collapse that happened Thursday in Cleveland.
The collapse claimed the life of a worker at Dillard Construction who was nine feet below the surface.

Coworkers tried to rescue the man, but were unable to. The rescue operation moved into a recovery phase once first responders determined the victim was no longer alive.

TOSHA explained to Local 3 News that an investigator was sent to the site to begin the inquiry that will determine the circumstances that led to the worker’s death.

Typically, the site is surveyed, company records are examined and interviews are conducted.

The investigation into a fatality can take as long as six months to complete.

TOSHA conducted a history search for Dillard Construction and did not locate any prior inspection, complaint by letter, or rapid response investigations involving the company.
Dillard Construction released the following statement:
 
"We are completely devastated by what occurred yesterday to one of our employees. We are fully committed to cooperating with the agencies that are investigating this tragedy. Our deepest thoughts and heartfelt prayers are with his family, friends, and coworkers during this incredibly difficult time."
