Three workers were killed and dozens more people were injured after the cranes collapsed on Oct. 12. The cranes were a source of major concern as they continued to sway after the accident.City officials ordered an evacuation of the area surrounding the partially collapsed hotel, located on the edge of the historic French Quarter, on Sunday morning. Demolition crews attached small explosives known as energetic materials to the cranes in an effort to bring them down in the same place as where they were standing several stories above the ground.The remains of two the deceased are still inside the unstable building, and first responders hope to retrieve them once the demolition was complete.Ten of the injured victims have filed a lawsuit against five companies involved in the construction.
