A hostage situation at the James T. Vaughn Correctional Center in Smyrna, Del., is over, nearly 24 hours after it began. Four prison staff members were initially taken hostage; one of them was declared dead early Thursday, after police secured the facility.Two of the hostages had been released Wednesday, as officials sought to negotiate with inmates. As Delaware Public Media's James Dawson reports for NPR's Newscast unit, state police entered the building at the center of the standoff around 5 a.m. Thursday."They found one employee alert and responsive," Dawson reports. "They took that employee to a hospital for evaluation. And the second one was unresponsive and later declared dead."We'll report more details as state officials speak about the case.During the standoff, inmates contacted local media to say they were angry about their treatment at the prison — and that they were concerned it would get worse under President Trump.The takeover began about 10:30 Wednesday morning when prisoners overpowered four correctional employees in building C, which houses more than 100 inmates.One hostage, who suffered non-life threatening injuries, was released in the afternoon and another hostage, whose condition is unknown, was released hours later.Robert Coupe, Delaware's Homeland Security secretary, said officials were willing to listen to the prisoners."If the inmates want to talk about conditions, privileges, those types of things, yes that dialogue can take place, but none of that starts until we have the safe return of our staff," Coupe says.The Associated Press reports:
