Ghost Ship fire started on the 1st floor, trapped people on second floor, ATF says

FRESNO, California (KFSN) -- The ATF said there was no evidence of fire alarms or fire sprinklers in the building.

Special agent in charge of the San Francisco office of the Bureau of Alcohol, Tobacco, Firearms and Explosives Jill Snyder said Wednesday people on the second floor of the warehouse did not know there was a fire on the first floor until it was well developed. There were two stair cases from the first floor to the second floor, but neither of them led to a building exit.

Snyder said the smoke went up the stairwells to the second floor, trapping the victims.
