NATCHEZ, Miss. (AP) — Three inmates charged with planning to kill a guard during a violent federal prison riot at Adams County Correctional Center will be tried June 8 in U.S. District Court in Jackson.

The Natchez Democrat reports the trial had been scheduled for Monday but defense attorneys for Hector Miguel Diaz-Osuna, Ernesto Granados and Juan Geraldo Arredondo asked for more time to prepare.

Prison guard Catlin Carithers was killed and 20 people were injured in the May 20, 2012, riot at the privately-run Adams County Correctional Facility in Natchez, which holds immigrants convicted of crimes while being in the U.S. illegally.

The prison holds nearly 2,500 inmates, most of them convicted on charges of coming back to the U.S. after deportation for being in the country illegally. The prison is operates by Nashville, Tennessee-based Corrections Corporation of America, one of the nation's largest private prison companies.

Several other inmates have been charged — or convicted — with participating in the riot, including Jesus BeltranRodriguez and Ricardo GonzalezPorras. Rodriguez and Porras have already pleaded guilty to second-degree murder.

DiazOsuna is charged with rioting, conspiracy to murder and a violation of the federal code protecting officers and employees of the United States. Arredondo and Granados are each charged with rioting.

Damage to the Adams County Correctional Center was estimated to be more than $1.3 million.
