Mexican National Sentenced to Life Imprisonment in the 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, a Mexican National, was sentenced in federal court today to life imprisonment. The sentence comes after a federal jury found Patron guilty 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 drug dispute.
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.
“Here’s a wakeup call to drug traffickers and cartel members in Tijuana: You harm an American, you will face American justice,” said U.S. Attorney Adam Gordon, “This sentence appropriately reflects the grim reality of drug trafficking in Tijuana. But, the FBI and U.S. Attorney’s Office will continue to secure justice for crimes against American citizens even if they occur south of the border.”
“Patron’s callous and blatant disregard for human life is unconscionable,” said Mark Dargis, Special Agent in Charge of the FBI San Diego Field Office. “Today’s life sentence is the price Patron must pay for such a gruesome attack on a U.S. citizen and the pain inflicted on his family. The FBI will always work relentlessly with our law enforcement partners devoting every available resource, tool, and technique at our disposable to hold violent criminals accountable and seek justice for our citizens.”
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.
At sentencing, a member of the victim’s family informed the Court that the Defendant “didn’t just take [the victim’s] life, he took a part of mine.” She continued, explaining that “every day, I wake up with pain that will never go away.” And closed by telling the Court, “I want [the Defendant] to carry the weight of what he did for the rest of his life.”
Judge Hayes addressed the Defendant and told him, “You literally walked the victim to his death.” Judge Hayes explained that the victim must have known at some point that he would be killed and, as the Defendant walked the victim down a deserted Tijuana hillside, the victim “knew that he was going to die alone, left with the trash on the hill.” But the Defendant did not care. “You executed him, turned around, walked up that hill and you left.” Judge Hayes added that the victim’s parents “will live with that until they die.”
Judge Hayes closed by sentencing the Defendant to life, as required by statute, on the hostage-taking resulting in death counts, and 420 months (35 years), followed by five years’ Supervised Release for intentional killing while engaged in drug trafficking. All counts to run concurrent.
Assistant U. S. Attorneys Mario Peia and Alexandra F. Foster prosecuted this case.
