SAN ANTONIO — This is an official press release from the U.S. Department of Justice (Drug Enforcement Administration (DEA)), published as received.

SAN ANTONIO – A Mexican national was sentenced in a federal court in San Antonio today to 384 months in prison for selling methamphetamine, possession of a firearm in furtherance of a drug trafficking crime, and illegal re-entry into the United States.

According to court documents, Ricardo Mujica-Calderon, 36, sold methamphetamine from his vehicle at a motel in San Antonio in January 2022. During a search warrant on his residence in April 2022, Mujica-Calderon fled through his backyard and was located approximately one block away. He falsely identified himself with a Mexican ID card in another person’s name. During his transport to jail, Mujica-Calderon slipped his left handcuff and became violent with a law enforcement officer, who was able to re-secure Mujica-Calderon.   

In the search of Mujica-Calderon’s home, Drug Enforcement Administration agents found 13 kgs of methamphetamine in a guest bedroom closet and five firearms in the master bedroom, several of which were loaded with extended magazines. Also in the master bedroom, DEA agents discovered a safe containing approximately 192.5 grams of methamphetamine and 227.7 grams of cocaine, as well as $12,725 and a semi-automatic pistol that had been reported stolen.

Mujica-Calderon was named in a six-count indictment on May 4, 2022. On Oct. 17, 2025, he pleaded guilty to one count of possession with intent to distribute more than 500 kgs of a mixture or substance containing methamphetamine, one count of possession of a firearm in furtherance of a drug trafficking crime, and one count of illegal re-entry into the United States. U.S. District Court Judge Jason K. Pulliam presided over the case.

“This successful prosecution of a felon with multiple convictions for illegal re-entry, assault of a family member, and a DWI with a child under 15 years of age is a great example of the level of collaboration that can be achieved between federal, state, and local law enforcement,” said U.S. Attorney Justin R. Simmons for the Western District of Texas. “In the Western District of Texas, we will continue to work with all of our law enforcement partners to hold criminal illegal aliens accountable for poisoning our communities and committing violent crimes.”

“Mujica-Calderon profited from peddling poison in our San Antonio neighborhoods,” said DEA Special Agent in Charge of the San Antonio Division Miguel Madrigal, "When DEA agents searched his home, they found not only lethal drugs but also numerous firearms, some of which were stolen. We've seen time and time again that when drugs and guns are together, violence is always looming. There will never be a place for those who bring about devastation to our communities.”

“ICE will continue working with our law enforcement partners to identify illegal aliens who are not only illegally present in this country, but also commit crimes and endanger our communities,” said ICE San Antonio Enforcement and Removal Operations Field Office Director Miguel Vergara. “ICE placed a detainer on this criminal illegal alien. Upon his release from custody, he will be transferred to ICE and deported to his home country.”

The DEA, ICE, Texas Department of Public Safety, and Devine Police Department investigated the case.

Assistant U.S. Attorney Eric Yuen prosecuted the case.

This case is part of Operation Take Back America, a nationwide initiative that marshals the full resources of the Department of Justice to repel the invasion of illegal immigration, achieve the total elimination of cartels and transnational criminal organizations (TCOs), and protect our communities from the perpetrators of violent crime.
