Jury: Defendant is Guilty of Hostage Taking and Murdering U.S. Citizen in Tijuana

For Immediate Release
U.S. Attorney's Office, Southern District of California

SAN DIEGO – Brian Alexis Patron Lopez was found guilty by a federal jury today for his role in the kidnapping, hostage taking, torture, and murder of 18-year-old M.A.R., a U.S. citizen whose death was punishment for a dispute over a stolen load of methamphetamine that was supposed to have been smuggled into the United States.

The jury deliberated for less than a full day at the end of a seven-day trial. The jury found Patron guilty on all counts, including Intentional Killing While Engaged in Drug Trafficking, Hostage Taking Resulting in Death, and Conspiracy to Commit Hostage Taking Resulting in Death.

“This is a heartbreaking tragedy, where a young man lost his life, leaving his family shattered,” said Acting U.S. Attorney Andrew Haden. “Drug traffickers are ruthless and will stop at nothing. But their resolve pales in comparison to the commitment of the United States to the safety of its citizens wherever they may be. This kidnapping and murder of a U.S. citizen happened in the dark corners and remote ravines of Tijuana, at the very beginning of the COVID-19 pandemic. With the incredible assistance of FBI San Diego and our Mexican counterparts, our prosecution team did not rest until justice was served for the victims of this heinous senseless cruelty.”

“Today’s verdict is an impactful outcome to a ruthless, vicious, and violent hostage taking and murder, and brings justice to the victim’s family,” said San Diego FBI Special Agent in Charge Stacey Moy. “FBI San Diego will continue to be a formidable force against drug cartels and cartel violence, which threaten the safety and security of Americans both here and abroad and devastate our communities.”

Patron is scheduled to be sentenced on July 7, 2025, before U.S. District Judge William Q. Hayes.

The victim was abducted from a hotel in Tijuana, Mexico on May 29, 2020. He was then beaten, tortured, and finally shot to death, all while his attackers sought a ransom from his family. His body was recovered on a hillside in Tijuana six days later.

According to evidence presented at trial, on May 29, 2020, at approximately 11:57 p.m., Patron and others forcibly removed the victim from his hotel room. Patron and others punched, kicked, and pistol-whipped M.A.R. Once subdued, the attackers put M.A.R. in a waiting car and drove away.

Patron and his co-conspirators then drove M.A.R. to Patron’s neighborhood, where they continued to beat and torture M.A.R. At around the same time, Patron and his co-conspirators began to make ransom demands on M.A.R.’s family over texts and calls, with the demand ranging from $2,000 to $3,000 to methamphetamine in exchange for M.A.R.’s release.

In the afternoon of May 30, 2020, Patron and his co-conspirators brought M.A.R. to a different motel and then to an apartment before bringing him to a deserted hillside on the night of May 30, 2020. There, Patron fatally shot M.A.R., even as his family attempted to pay his ransom.

During the trial, the government presented evidence connecting Patron to the crimes, including Facebook messages between Patron and co-conspirators about the crimes, plus surveillance video that captured the kidnapping outside a Tijuana hotel. In that video, Patron wore a jacket that matched the one he wore earlier in the night. Patron’s bracelet was left behind at the kidnapping and was later recovered by law enforcement. Patron was wearing the same bracelet in Facebook photos posted before the murder. Jurors were also presented with the call logs and WhatsApp messages with the ransom demands and proof-of-life evidence.

Assistant U. S. Attorneys Mario Peia and Alexandra F. Foster prosecuted this case.
