Back in April 2022, seven defendants, including Rivas-Moreiera, were indicted and charged with the planning and execution of a violent attack orchestrated by members of MS-13 against Mexican Mafia and Sureños associates that resulted in two deaths in Beaumont’s Federal Prison.

On January 31, 2022, seven MS-13 members imprisoned at the U.S. Penitentiary in Beaumont attacked multiple Sureños members and one Mexican Mafia associate.

Rivas-Moreiera began the prison attack when he approached Guillermo Riojas and stabbed Riojas twice in the chest.

Rojas immediately collapsed, then the rest of the MS-13 members fell upon him, brutally kicking and stabbing the man until he lay motionless on the ground.

The MS-13 defendants then chased, cornered, beat, and repeatedly stabbed Andrew Pineda, and other Sureños members.

The prison attack lasted approximately three minutes and Riojas and Pineda died as a result of the attack.

This fight between the gangs resulted in a nationwide lockdown of all inmates in the Federal Bureau of Prisons for almost a week.

Defendants Rivas-Moreiera, Alfaro-Granado, and Landaverde-Giron are all serving sentences of life imprisonment for their participation in MS-13 and committing murder in aid of racketeering in furtherance of MS-13. 

Defendant Ramires is also serving a sentence of 27 years in federal prison following his conviction for participating in MS-13 and committing a murder on behalf of the gang.

Rivas-Moreiera admitted to his role in the deadly prison attack and faces a maximum sentence of life imprisonment. He was the last remaining defendant to plead guilty.
