A New Castle County jury has found one inmate guilty of murder following the four-week trial of three men charged in the killing of Lt. Steven Floyd during a prisoner uprising at Delaware’s James T. Vaughn Correctional Center last year.

The 12-member jury late Tuesday found Dwayne Staats guilty of first-degree felony murder and murder of a law enforcement officer after three days of deliberation in the first of several planned trials stemming from the violent takeover in February 2017. Staats, who admitted to planning the takeover to protest prison conditions, was also found guilty of riot, kidnapping, assault and conspiracy.
