PENSACOLA, Fla. — The jail already had two feet of water in the basement from the record-setting rains when an apparent gas explosion leveled the inside of the building, killing two inmates and injuring more than 180 other people, officials said Thursday. In the rubble and chaos, inmates were trapped and had to be rescued. Others were treated for their injuries in the parking lot. In all, 600 inmates rushed out of the jail. The injured were taken by bus to hospitals while the others were sent to nearby jails. Authorities lost track of three inmates in the confusion, but by late afternoon, they were confident everyone was accounted for.Inmate Monique Barnes told The Associated Press by telephone that she was knocked off her fourth-floor bunk. “The explosion shook us so hard it was like we were in an earthquake,” Barnes said. “It was like a movie, a horrible, horrible movie.”Pieces of glass, brick and inmates’ flip-flops were strewn about on the ground outside the jail. The front of the building appeared bowed, with cracks throughout.Barnes, who spoke to AP after she was taken to another jail, said she and other inmates complained of smelling gas ahead of the blast, and some reported headaches.
