San Diego smuggler gets 12 years as victims' families describe ransom calls and beatings
Isaac Jimenez, a 30-year-old U.S. citizen from San Diego, was sentenced Friday to 12 years in federal prison for his role in a human smuggling operation that led to the kidnapping and deaths of two people in Mexico, Courthouse News Service reports. U.S. District Judge Janis Sammartino also ordered Jimenez to pay $24,500 in restitution.
Both victims had paid smugglers to bring them illegally into the United States. Instead, they were held captive in Mexico, their families extorted for ransom. Neither body has been recovered.

"Time had just stopped"
The father of 20-year-old Vivianna Aguirre, identified in court as Jose, described receiving a phone call from his daughter on the night of December 5, 2024. Speaking through a Spanish interpreter, he told the court she had been kidnapped and was pleading with him not to contact police.
"When I told her I was going to call the police, she begged me desperately not to do that because they had threatened to kill her," Jose said. "It felt as though time had just stopped and I wanted her to tell me it was a joke, but it was real … Nothing that the court does will be able to return my daughter."
In the days that followed, Jose said he received video calls showing Aguirre being beaten, with firearms pointed at her. The family paid thousands of dollars to the kidnappers. She was never released. Aguirre's family has since recovered teeth and bone fragments believed to belong to her.
Jimenez had originally been hired to facilitate Aguirre's transportation from Tijuana to the United States so she could reunite with her boyfriend — a man Jimenez had previously smuggled across the border. Despite the family's payments, she was never freed.
"Nothing can erase the sound of her voice when she was so scared, or the images they made us witness," Jose told the court. "But a meaningful penalty can show us that her life mattered and that the suffering caused to our family matters."

"All Carlos wanted was to come home"
Jennifer Martinez, wife of 30-year-old Carlos Cabrera, addressed Jimenez directly, describing the moment she learned her husband had been taken. Cabrera had been traveling to Orange County to reunite with his family when he was kidnapped.
"'You need to pay the money or they're going to put a bullet through my head,'" Martinez recalled through tears. "Those words and the fear I heard in his voice have never left."
Martinez said she followed every instruction the kidnappers gave her, hoping compliance would bring her husband home. "All Carlos wanted was to come home to his family," she said. "You took that away from him."
Like Aguirre, Cabrera's body has not been recovered.

Jimenez apologizes, says role was limited
Jimenez turned to face the victims' families in court and apologized, speaking through a Spanish interpreter. "For a long time I thought I was helping people, and I now realize it was never that way," he said. "Because of the decisions and my friendships, they did something terrible to the family, and I will always have to live with that. I regret it."
He maintained that his role in the operation was limited and that he did not personally hold either victim hostage. "I don't know what happened to your family members. I don't know where they are," he told the courtroom.
His attorney, Douglas Brown, argued that the smuggling operation had grown significantly more dangerous in recent years due to cartel activity, and that Jimenez had been threatened with death if he refused to participate. Jimenez eventually turned himself in to authorities. He pleaded guilty in June.
According to the Department of Justice, Jimenez had been involved in human smuggling since at least 2015. DOJ attorney Robert Miller told the court that although Jimenez did not personally hold the victims captive, he was aware as early as September 2024 that his co-conspirators were holding people against their will. The co-conspirators are believed to have been killed or imprisoned in Mexico.

Judge: "You preyed upon the most vulnerable people"
Judge Sammartino, a George W. Bush appointee, said the killings represented the most deliberate and unnecessary loss of life she had encountered in a long time.
"These family members that are here to address the court made desperate effort to meet the demands asked by the kidnappers and did everything they could, and saw their family members being tortured and abused," Sammartino said before imposing the sentence. "You knew the business of smuggling well. You preyed upon the most vulnerable people."
Miller, speaking to Courthouse News outside the courtroom after sentencing, said that extortion tied to smuggling in Mexico is likely significantly underreported, given the difficult circumstances facing victims and their families on both sides of the border. He thanked those families for cooperating with law enforcement.
"Smugglers are not benevolent actors," Miller said during proceedings. "They are motivated by profit, and they are violent and inhumane."
