Investigators are trying to figure out what caused a raging fire at an abandoned D.C. school building.
The two alarm fire started just after 11:00 p.m. at the old Webb Elementary School.
Firefighters battling the flames had to evacuate the building forcing them to attack the fire from the outside.
Webb Elementary School was shut down in 2008 and the building was most recently used as a warehouse.
