JACKSON, Miss. (AP) -- An inmate suspected of participating in the fatal beating of a guard during a prison riot in Mississippi last year is expected to plead guilty next month.
Prosecutors say Marco Perez-Serrano, also known as Jesus Fernando Ochoa, was the first inmate to attack correction officer Catlin Carithers during the riot at the privately run Adams County Correctional Facility in Natchez on May 20, 2012.
Carithers died and 20 people were injured as the riot grew to involve hundreds of inmates.
Perez-Serrano is charged with rioting. A change of plea hearing is scheduled for Aug. 13 in U.S. District Court in Natchez.
Court records say Perez-Serrano hit Carithers with a food tray before others attacked.
The prison holds inmates who were convicted of crimes while being in the United States illegally.
