Three former South Texas police officers are facing arraignment on charges that they accepted money in exchange for escorting drug shipments.

Former Mission Police officers Jonathan Trevino and Alexis Espinoza are both sons of prominent South Texas Law Enforcement officials.

The Hidalgo County Sheriff, Lupe Trevino, is the father of Jonathan Trevino. Also, Hidalgo Police Chief Rodolfo “Rudy” Espinoza is the father of Alexis Espinoza.

Along with Trevino and Espinoza, former Hidalgo County Sheriff’s Deputy Gerardo Mendoza-Duran has also been indicted. The three were indicted last week after being arrested along with a fourth former officer in December.

The fourth ex-officer, former deputy Fabian Rodriguez, plead not guilty Monday.

The charges they face include: conspiring to possess cocaine with intent to distribute, aiding and abetting.

According to the indictment, the former officers accepted thousands of dollars in bribes to escort loads of drugs that were part of a federal sting operation.
