Two people died after being taken to the hospital, and two more were found dead in the rubble, said Michael Schurman, a spokesman for the Atlantic County Office of Emergency Management. All of those killed were construction workers and all of the injured are too. Of the 21 people hospitalized after the 10:30 a.m. EST collapse of a portion of the Tropicana Casino and Resort parking structure, four are in critical condition, a hospital spokeswoman said.
