NATCHEZ — Four inmates were sentenced Thursday for their participation in the May 20, 2012, prison riot at the Adams County Correctional Center.

A news release from the U.S. Department of Justice said Judge David Bramlette III handed down the sentences to:

-Ruben Coronado-Licon, 24, originally of Delicias, Chihuahua, Mexico, who was sentenced to 66 months in federal prison.

-Jorge Felix-Ibarra, 31, originally of Sinola, Mexico, who was sentenced to 57 months in federal prison.

-Joel Oswaldo Ramirez-Nunez, 36, originally of Ciudad Juarez, Mexico, who was sentenced to 92 months in federal prison.

-Hector Miguel Diaz-Osuna, 35, originally of Sinola, Mexico, who was sentenced to 300 months in federal prison.

The four men were also ordered to pay restitution — jointly and individually — in the amount of $1,382,313.

They face deportation following the serving of their sentences.

During the riot, inmates stacked food carts in order to access the roof of the building on which Sgt. Catlin Carithers was standing as part of his response to the attack. Inmates assaulted Carithers with their hands, feet and improvised weapons, including a broom and a metal pole, Assistant U.S. Attorney Patrick Lemon said in previous hearings for other inmates.

An autopsy later concluded Carithers — who was deploying crowd control gas from the roof at the time of the attack — died of blunt force trauma associated with his injuries.

The riot, which lasted for several hours, initially started as an organized mass disobedience by the prisoners, who told investigators they were trying to take a list of demands to prison officials to address what the prisoners perceived as issues with food quality, medical care and disrespectful guards.
