According to Pete Piringer, the public information officer for D.C. Fire and EMS, units arrived on the scene just after 8 a.m. to a "pretty significant fire." The fire was concentrated in the repair shop. Piringer said there was significant damage and a blaze spread to the side of the shop in either a pile of rubble or a car. He was not on the scene at the time and could not confirm.
It is unclear at this time what started the blaze.
