Harrowing new details are emerging about the moment the building in Miami collapsed. Resident Cassie Stratton frantically called her husband at 1:30 a.m. and told him the building's pool was collapsing. Then, the phone went dead. Stratton, a model, is among the 151 residents still missing. Her chilling last words appear to confirm theories that the collapse began at ground level and not from the top-down. 120 rescuers are working grueling 12-hour shifts in search of 151 people still missing. #InsideEdition
