A leaked diplomatic cable shows the Trump administration ordered U.S. officials in Spain to investigate how a 25-year-old woman who was repeatedly sexually assaulted ended up choosing to die, and why no one was ever charged for the attacks against her.
Noelia Castillo died last Thursday in a Barcelona hospital after receiving three injections that stopped her heart within 20 minutes. Spain approved her euthanasia request in 2024 under a law the country passed in 2021 that permits the procedure for those suffering severe psychological distress. Her father spent 18 months fighting in court to stop it.
Now the State Department has ordered its embassy to confront Spanish authorities by Friday, April 3, raising what the cable calls "many systemic human rights failures" in the case. The move has ignited a diplomatic confrontation between Washington and Madrid at a moment when Spain's socialist prime minister, Pedro Sanchez, has already been clashing with the Trump White House on multiple fronts.
The diplomatic cable, reported by The U.S. Sun, instructed American officials in Spain to investigate how Castillo "ended up choosing death." It told them to identify her alleged attackers and explain why no criminal charges were ever brought.
The language in the cable is blunt. One passage reads:
"We are deeply concerned by allegations that Ms. Castillo was repeatedly sexually assaulted while under state care and that no perpetrators have been brought to justice."
Another section raises questions about whether Castillo's consent was genuine in her final hours:
"We are also aware of reports that Ms. Castillo expressed hesitancy to undergo euthanasia in her final hours, but that these indications were ignored."
The cable also flags the broader legal framework. It states the case "raises serious concerns about the application of Spain's euthanasia law, particularly in cases involving psychiatric conditions and non-terminal suffering."
And then it goes further, into territory that clearly touched a nerve in Madrid. The cable states that U.S. officials are "investigating allegations that the sexual assault of Ms. Castillo was perpetrated by individuals of a migration background." It adds: "Mass and illegal migration is a human rights concern, and Spain's facilitation of mass and illegal migration represents a dangerous threat to the rights and liberties of Spanish citizens."
Noelia Castillo survived a suicide attempt that left her paralyzed from the waist down. Spanish outlet Antenna 3 reported her final words before the procedure: "I want to go now in peace and stop suffering."
She asked to go through her final moments alone. "I don't want them to see me closing my eyes," she said, according to the same report. She also told her parents: "The happiness of a father or mother cannot be more important than that of a daughter."
Her mother, Yolanda Ramos, stayed by her side through the night before the procedure, praying for a change of heart. "I've been praying and thinking... hoping that at the last moment she'll say 'I regret it,'" Ramos said.
Outside the Barcelona hospital, Noelia's best friend sobbed after being denied one final chance to stop the procedure. Her father, whose name has not been publicly reported, had led the 18-month legal battle to block it. He argued that Noelia's mental health meant she could not make a "free and conscious decision." Footage showed him cheering her on as she tried to walk again on crutches.
Spanish judges ruled otherwise. Courts found Castillo's choice was "free, conscious and informed." Spain's Supreme Court upheld what it called her "right to die," as the New York Post reported.
Spain's health minister, Monica Garcia, responded to the Trump administration's intervention with a post on X that pivoted immediately to attacking the United States. She wrote:
"In the United States, thousands of people without health insurance die every year, whilst Trump supports and carries out human rights violations in Gaza and Iran."
Garcia added that "Spain is a serious country, with a robust healthcare system and a framework of rights that protects and cares for everyone, including those who choose to seek assistance to die with dignity in contexts regulated by law, assessed by clinical committees and endorsed by the courts."
Garcia also said Trump "should stop feeding the ultra-international agenda by sticking his nose into every single place." Catalonia's regional government similarly condemned Washington's involvement and defended Spain's euthanasia framework.
Notice the pattern. When confronted with specific allegations, that a sexual assault victim received no justice, that her last-minute hesitancy may have been ignored, that the attackers were never charged, Spain's officials changed the subject. They talked about American health insurance. They talked about Gaza. They talked about sovereignty. What they did not do is answer the questions in the cable.
This confrontation does not exist in a vacuum. Pedro Sanchez has repeatedly clashed with the Trump administration. He branded the U.S.-backed Iran conflict "absurd and illegal" and called it "much worse" than Iraq. He refused American requests to use Spanish military bases.
The Castillo case now adds a human-rights dimension to a relationship already strained by security disagreements. The Trump administration's willingness to press the issue, through official diplomatic channels, with a specific deadline, signals that this is not a passing comment but a deliberate policy action. The administration has shown a similar willingness to press uncomfortable questions through official channels on other fronts, as seen in recently released details about investigative probes and legal protections.
The New York Post reported that U.S. State Department officials specifically directed the embassy in Madrid to investigate how Spanish law enforcement handled repeated sex attacks against Castillo before her euthanasia. The Post also noted allegations of a conflict of interest involving the doctor who performed the procedure, a detail that raises additional questions about the integrity of the process.
The leaked cable raises questions that Spanish officials have so far declined to address directly. Who attacked Noelia Castillo? Why were no charges brought? What investigation, if any, did Spanish law enforcement conduct into the alleged assaults? Were the attackers identified?
And perhaps most troubling: if Castillo expressed hesitancy in her final hours, what protocols existed to pause the procedure? Who made the decision to proceed? Spain's euthanasia law requires that the choice be free and conscious. If a patient wavers at the last moment, what happens next?
These are not rhetorical questions. They are the questions the diplomatic cable explicitly told American officials to raise with Spain. The April 3 deadline has arrived. Whether Spain answers them, or continues deflecting toward American health insurance statistics and foreign policy grievances, will say a great deal about how seriously Madrid takes the case of a young woman who suffered under its care.
Strip away the diplomatic maneuvering and what remains is a grim sequence. A young woman was allegedly gang-raped. No one was charged. She attempted suicide and was left paralyzed. She applied for euthanasia on psychological grounds. Her father fought for a year and a half to stop it. Courts overruled him. Reports suggest she wavered in her final hours. She died anyway.
Spain's officials want to frame this as a matter of sovereignty, an American president meddling in their internal affairs. But sovereignty does not excuse a system that allegedly failed to prosecute violent criminals, then approved the death of their victim. Those are not competing political narratives. Those are facts that demand an accounting.
Monica Garcia can talk about American health insurance all she wants. The question on the table is simpler: What did Spain do for Noelia Castillo while she was still alive?
