SPRING CITY, Tenn. (AP) — A construction worker died after he was trapped in a trench that collapsed while he was working on a home in Tennessee, authorities said.

The man, who was not identified, was working in the garage of a home under construction when a trench dug as part of the project collapsed Saturday afternoon in Rhea County, said Det. Rocky Potter, a spokesman for the county sheriff’s department.

Rescue crews from Chattanooga, Knox County and other jurisdictions were called in to help with a rescue attempt. Crews dug with hand tools such as shovels because there was no room in the garage for mechanized equipment, Potter said.

The man was found dead at about 1 a.m. on Sunday, Potter said. Seventy to 100 rescue workers and members of law enforcement and fire departments worked on the scene of the rescue attempt, Potter said.

The home is located near Spring City, which is about 55 miles (88 kilometers) north of Chattanooga.
