The body of a man trapped in a Landover warehouse was recovered Sunday morning following a 58-hour recovery effort, fire officials said.
Prince George's County fire and rescue crews had been working since 10 p.m. Thursday at 1501 Cabin Branch Drive, where the roof of a warehouse had collapsed, said Mark Brady, spokesman for the department.
The remaining 11 to 15 employees in the building at the time of the collapse--caused by a forklift accident--escaped the building unharmed.
Family members of the trapped employee, who will not be identified until an autopsy is complete, have been on the scene since Thursday evening, as contractors worked to remove 40 to 50 feet of debris to locate the man.
"This was treated as a rescue operation," Brady said. "We maintained that frame of mind up until we found the body."
The Maryland Occupational Safety and Health Agency will conduct an investigation into the collapse, Brady said.
Rescue efforts included 75 fire and EMS personnel, a K-9 search for the man and assistance from the collapse unit from the District of Columbia Fire Department, Brady said. The search had to be put on hold Friday morning so structural engineers could evaluate building stability before deciding on using the cranes for debris removal, according to county fire officials.
The warehouse is 60 years old, according to online state Department of Assessments and Taxation records.
