Another call came in 12 seconds later “...We’re calling in a fire alarm for a business.” There’s no evidence at this point of a fire or explosion prior to collapse. But Gabriel Nir, a survivor who lived on the first floor of the building just above the underground garage told NBC 6 he heard and felt what he called “the first collapse.” “The first collapse happened. Me and my mom, my sister went out first collapse,” Nir said. “We see the collapse happening on the pool side and I saw a bunch of cars like going in, inside the car garage,” Nir said.
