A 48-year-old construction worker was pulled from the rubble of a collapsed building after an hour and half of being trapped. He was transported to the hospital where he was later pronounced dead from injuries sustained.

Fire officials have not determined the cause of the explosion that caused a residence for people 55 or older to collapse upon construction workers. Initial reports lead officials to believe that the accident was caused by the construction work going on in the basement that may have released propane rapidly and been triggered by an unknown cause.

Four other workers and two firefighters were also injured in the accident. All but two of the workers have been treated and released, but the other two are listed in stable condition.

Construction accidents can cause serious injury and can happen very unexpectedly, our thoughts are with the friends and family of the victim.
