JACKSON (AP) — A change of plea hearing has been scheduled for Feb. 26 for an inmate charged with participating in a deadly prison riot in Mississippi.

One guard was killed and 20 people were injured in the May 20 riot at the privately-run Adams County Correctional Facility in Natchez, which holds illegal immigrants convicted of crimes in the U.S.

A filing in U.S. District Court in Natchez says Yoany Oriel Serrano-Bejarano plans to change his plea to guilty.

A complaint filed by an FBI agent says Serrano-Bejarano assaulted a guard and helped other inmates climb onto the roof of a building where correction officer Catlin Carithers was beaten to death.
