Officials tell News 12 Long Island they ran into some challenges while trying to get straps under the boat because the back end is stuck in mud, 60 feet underwater. Once they're able to get straps under the boat, divers will place air bags around the vessel, inflate them and bring the vessel to the surface. Officials hope the boat holds answers as to why the boat capsized and whether there were enough life jackets for all 27 people onboard. Police say 27 people were headed back from watching fireworks in the waters off Oyster Bay when their boat capsized, killing three children who were trapped in the cabin of the yacht. The boat operator, Sal Aureliano, told News 12 Long Island exclusively that they were hit with a rogue wave.Investigators say there could be evidence on the boat that could determine the exact cause of the tragic capsizing. The FBI will resume efforts to recover the boat at 8 a.m. tomorrow.
