Authorities have identified a worker who was killed in a trench collapse at a Lee's Summit home that was under construction.

Lee's Summit Police Sgt. Chris Depue said in a news release Friday that the victim is 49-year-old Brian D. Allen of Windsor. Emergency crews were called at 1:30 p.m. Thursday to the scene where a 75-foot trench had been dug from the street to the house so crews could connect a sewer line.

Depue says the earth shifted in the trench and collapsed on the worker, while a second worker at the top of the trench was not harmed.

Rescue crews tried frantically to dig the victim out before the trench began to collapse again and they shifted to recovery mode.

Authorities didn't immediately release the company involved.
