JACKSON (AP) — Two people indicted for their roles in a Natchez prison riot that left a guard dead have each been sentenced to several more years in prison.

Carlos Flores, 42, and Yoany Oriel Serrano-Bejarano, 29, were charged with conspiring to cause a riot at the privately run Adams County Correctional Center in May 2012.

Flores pleaded guilty in May. U.S. District Judge David C. Bramlette III on Thursday sentenced him to just over six years in prison. Federal prosecutors said Flores conspired with others to cause the riot.

Serrano-Bejarano pleaded guilty in February to participating in the riot and Bramlette sentenced him to six years also.

The prison is owned by Nashville, Tennessee-based Corrections Corporation of America, one of the nation’s largest private prison companies. During the riot, several corrections officers were assaulted and one officer, Catlin Carithers, died from his injuries. Other guards were held hostage for several hours before authorities suppressed the riot that caused an estimated $1.3 million in damage.

Each inmate also was ordered to pay restitution in the amount of $1.3 million.

Authorities said prisoners took food service carts out of the dining hall and kitchen and stacked them on top of each other to climb onto the roof where Carithers was beaten. Serrano-Bejarano was identified in court records as one of the inmates who held the food carts for the other prisoners.

The prison held nearly 2,500 inmates, most of them convicted on charges of returning to the U.S. after deportation for being in the country illegally.
