NATCHEZ — An inmate involved in the May 20, 2012, prison riot at the Adams County Correctional Center has received a six-year, three-month prison sentence for his role in the prisoner uprising.

U.S. District Judge David Bramlette III sentenced Adrian Romero-Carrera, 27, in Natchez Tuesday. Bramlette also ordered the inmate to pay $1,350,113 in restitution.

Romero-Carrera’s sentence will be followed by three years supervised release.

Romero-Carrera was indicted along with nine others in July. The indictment reads that the inmates “willfully instigated, connived, attempted to cause, assisted and conspired to cause a mutiny at the Adams County Correctional Center.”

An unredacted version of the full indictment was restricted from public access by the court.

Romero-Carrera originally pleaded not guilty to the charges, but changed his plea in November.

During the riot, one guard — 24-year-old Catlin Carithers — was killed after inmates climbed to the roof where he was deploying crowd-control gas and bludgeoned him with a blunt object.

Other guards were injured and taken hostage during the riot, as well as a number of inmates, and the prison sustained an estimated $1.3 million worth of damage.

Prison officials later said approximately 700 of the nearly 2,500 inmates housed at ACCC participated in the nearly seven hours of violence and looting.

ACCC is a federal immigration prison privately operated by Corrections Corporation of America.
