UPDATE: Del. AG responds to lack of charges following prison hostage incident

The Delaware Department of Justice is responding after comments made by Delaware Governor John Carney on the lack of criminal charges following a February prison hostage situation.

At a press conference Tuesday highlighting corrective action steps Governor Carney plans to take, he told reporters that he was "disappointed" no criminal charges have filed since the incident at the James T. Vaughn Correctional Center.

A total of four prison employees were held hostage during the roughly 19-hour stand-off, resulting in the death of Lieutenant Steven Floyd.

A statement from the state DOJ released to 47ABC on Wednesday confirms the criminal investigation is ongoing.  

"The singular goal of the police and prosecutors working on this investigation is to ensure that it is done thoroughly, so that those responsible for Steven Floyd's murder are held accountable," a statement from DOJ spokesman Carl Kanefsky reads. "Their job is complicated in this case by the sheer number of potential witnesses and defendants, and the fact that most of them are prison inmates."

Carney's comment Tuesday came as he responded to an independent report describing James T. Vaughn Correctional Center as dangerously overcrowded, critically understaffed, and poorly run and managed.
