Crews searched the inside of the roughly 5,000-square-foot warehouse but did not find anyone camping in or by the building who might have started the fire accidentally. In addition, a hydrocarbon-sensitive arson dog went over the area but did not hit on any accelerant, according to Deputy Fire Marshal Pat Killion.
Killion said the building burned from the top on down, which could mean fireworks landing on the roof ignited the blaze but no evidence of that had been found by the end of the day.
He was fairly certain the fire began sometime around 2 a.m., since a fire engine had been dispatched about 1 a.m. to a medical incident at nearby apartments, but no flames were noted at that time.
No injuries were reported and the fire was contained to warehouse, not threatening either the TRAX station at 4400 South or apartments a block north.
A dollar estimate for losses was yet to be assessed, but the warehouse containing automotive items was heavily damaged.
