SAN ANTONIO (AP) — A 38-year-old Texas Mexican Mafia leader has pleaded guilty to all federal charges against him, including charges related to the slaying of a San Antonio-area police officer and four other gang members.

San Antonio TV station WOAI reports ( ) that Ruben "Menace" Reyes admitted he ordered the 2014 slaying of Balcones Heights Police Officer Julian Pesina, who Reyes said also claimed to be a member of the criminal organization.

The San Antonio Express News reported earlier that Pesina had been under investigation.

According to a federal indictment, Pesina claimed to be a gang member. When the gang looked at his Facebook page, they saw he identified himself as a police officer.

Reyes faces a life prison sentence when he returns to court in September for his sentencing hearing.
