One employee is missing at a warehouse at 1501 Cabin Branch Drive in Landover where a roof collapsed at about 10 p.m. Thursday. Firefighters who arrived on the scene found that about 90 percent of the roof of the building had collapsed and the wall of the warehouse bowed out to as much as 45 degrees.
According to fire officials, firefighters "worked under a great risk of a secondary collapse and exercised all required precautions in an attempt to locate the employee." They have focused on a part of the building where the missing worker was last seen working in the warehouse. Officials say the area contains "building debris, fallen storage racks and boxes and boxes of paper files."
