DEL RIO, Texas – A leader of the Partido Revolucionario Mexicano prison gang, known as the PRM, was sentenced in federal court in Del Rio to 300 months, or 25 years, in federal prison for conspiracy to possess with intent to distribute heroin, according to the U.S. Attorney’s Office for the Western District of Texas.

Louis Iglesias, also known as “Wicho,” 56, of Rosenberg, was sentenced Thursday, Nov. 5, by Chief U.S. District Judge Alia Moses, according to the release issued Tuesday, Nov. 10, by U.S. Attorney Justin R. Simmons. The office described Iglesias as a PRM general.

What Prosecutors Say Happened

According to court documents, Iglesias was arrested on a bench warrant in April 2022 while he was already incarcerated with the Texas Department of Criminal Justice. The arrest came out of a federal investigation that began in March 2019 and targeted the trafficking and distribution of narcotics by the PRM prison gang.

Agents uncovered several phone conversations between Iglesias and co-conspirators that involved obtaining, dividing and distributing heroin, according to the U.S. Attorney’s Office. In one of those conversations, Iglesias instructed a co-conspirator to sell 250 grams of heroin.

Iglesias was charged in a federal indictment on June 9, 2021. At that time he was already serving 39 years in state prison for multiple convictions, including engaging in organized criminal activity, criminal solicitation of capital murder and having a prohibited item in a correctional facility. He pleaded guilty to one count of the federal indictment on Nov. 7, 2022, according to the release.

Part Of Operation Tequila Sunset

The DEA and FBI led the investigation, known as Operation Tequila Sunset. Homeland Security Investigations, the U.S. Marshals Service, the U.S. Border Patrol, the Texas Department of Public Safety, the Eagle Pass Police Department and the sheriff’s offices in Maverick, Dimmit and Val Verde counties assisted, according to the U.S. Attorney’s Office. The Bureau of Prisons National Gang Unit was also credited as instrumental in the case.

Several others in the case have already been sentenced. In June 2025, seven PRM members were sentenced to a combined 137 years in federal prison. Carlos Eduardo Saldana Jr. was sentenced in August 2023 to 120 months, Kevin Ritchie received 420 months in October 2023 and Clinton Ritchie was sentenced in July 2024 to 235 months, according to the release.

Assistant U.S. Attorney Brett Miner prosecuted the case. The office said the case is part of Operation Take Back America, a Justice Department initiative aimed at illegal immigration, cartels, transnational criminal organizations and violent crime.
