Mexico Seeks Answers After Royer Pérez Jiménez, March 16, 2026, 13th Death

(UNITED STATES) — Mexico demanded answers after 19-year-old Royer Pérez Jiménez died on March 16, 2026, in U.S. immigration detention, a death that Mexican officials said marked the 13th death of a Mexican national in immigration custody or enforcement operations since January 2025.

The case quickly became both a human-rights issue and a diplomatic dispute. Mexican officials publicly condemned the rising toll, while U.S. immigration authorities issued their own account of what happened at the Glades County Detention Center in Moore Haven, Florida.

President Claudia Sheinbaum sharpened Mexico’s response on March 20. “This can’t be happening. The report says the young man killed himself. Nonetheless, we want a full investigation. We’re going to use all measures to make our protests and support the family in everything they need.”

Mexico’s Foreign Ministry, known as the SRE, set out its position in Press Release 059/2026 on March 20. “The Mexican government reiterates that such deaths are unacceptable and again demands a prompt and thorough investigation to establish the circumstances surrounding this death, determine accountability, and put in place effective guarantees of non-recurrence.”

Those statements came after U.S. authorities disclosed Pérez Jiménez’s death and described it as a presumed suicide whose official cause remained under investigation. The dispute over the circumstances, and over conditions inside detention centers more broadly, has pushed the issue beyond one case and into the wider U.S.-Mexico relationship.

ICE said in a March 18 press release that “Royer Perez-Jimenez, 19, a criminal illegal alien from Mexico. passed away March 16 at the Glades County Detention Center in Moore Haven. He died of a presumed suicide; however, the official cause of his death remains under investigation.”

The agency added: “At intake, Perez was evaluated by medical staff. He denied any behavioral health issues or concerns and answered ‘no’ to all suicide screening questions.”

The sequence of public statements in March showed how quickly the case escalated. Pérez Jiménez died on March 16, 2026. Two days later, ICE issued its press release. On March 20, Mexico’s Foreign Ministry demanded what it called a prompt and thorough investigation, and Sheinbaum said Mexico would support the family and use all available measures to press its protest.

By March 25, the language from Mexico had grown sharper. Roberto Velasco, Undersecretary for North America, said during a media briefing that the deaths of 13 Mexican citizens in immigration operations or ICE custody between 2025 and 2026 were “unacceptable, painful and heartbreaking.”

Velasco also said Mexico would pursue “all diplomatic and legal avenues” to ensure accountability. That wording signaled that the Mexican government was treating the deaths not as isolated consular cases, but as an issue requiring a wider state response.

How the Numbers Shaped Mexico’s Response

The numbers behind the dispute have added force to Mexico’s demands. As of March 18, 2026, an estimated 46 individuals had died in ICE custody since January 2025. Within that broader toll, 13 Mexican nationals had died in U.S. immigration custody or during enforcement operations since January 2025.

The pace in 2026 has drawn added attention. At least 13 total immigrants of all nationalities died in ICE custody in the first three months of 2026 alone, compared with 31-33 deaths recorded in the full year of 2025.

Pérez Jiménez’s age made his death stand out even within those figures. At 19, he was reportedly the youngest person to die in ICE custody since the start of the current administration.

That detail gave his case immediate weight in Mexico, where officials were already tracking a rising number of deaths involving their citizens. It also fed criticism from advocacy groups, which have argued that detention conditions and access to medical and mental-health care need closer scrutiny.

ICE has defended its standards of care in broader policy statements. “ICE is committed to ensuring that all those in custody reside in safe, secure and humane environments. Comprehensive medical care is provided from the moment individuals arrive and throughout the entirety of their stay. At no time during detention is a detained alien denied emergency care.”

Still, the tension between that position and Mexico’s public condemnation has widened as more names have become part of the record.

Other Deaths That Have Drawn Attention

Among the Mexican nationals whose deaths have drawn attention is Alberto Gutiérrez Reyes, 48, who died February 27, 2026, in California. His case was described as involving a medical emergency and chest pain.

Another was Heber Sanchez Domínguez, 34, who died January 7, 2026, in Georgia. The reported circumstances said he was found hanging in quarters.

Jesus Molina-Veya, 45, died June 7, 2025, in Georgia. His death was described as a suicide.

Pérez Jiménez’s death on March 16, 2026 became the latest case in that sequence and, for Mexican officials, the one that pushed the count to a politically charged threshold: the 13th death of a Mexican national since January 2025.

Some of the reported causes and circumstances in these deaths remain under investigation, while others come from agency statements released after the deaths. That distinction has shaped how officials and advocates describe the cases.

Mexico has framed the issue around accountability and prevention. Its demand for “effective guarantees of non-recurrence” pointed not only to finding out what happened in one facility, but to preventing future deaths.

Detention Conditions and Broader Scrutiny

The broader detention picture has intensified scrutiny. The detained population surpassed 68,000 as of February 2026, roughly 70% higher than earlier levels under the current administration.

That rise has coincided with a shift toward interior enforcement and mass deportation strategies. As detention populations climbed, deaths in custody reached what was described as the highest level seen since 2004.

A larger detained population does not by itself explain individual deaths, but it has brought more attention to medical care, mental-health care, staffing and monitoring inside detention centers. It has also made each death part of a wider debate over whether the system can safely absorb that growth.

The facility where Pérez Jiménez died has become part of that debate. Glades County Detention Center had been shut down by the Biden administration and reopened under the current administration.

Its reopening, combined with the death of a 19-year-old detainee there, turned the center into a symbol of the concerns raised by Mexico and advocacy groups. The case linked detention expansion, facility use and diplomatic pressure in a single episode.

Mexican officials have also raised the possibility of further action beyond public protest. Velasco’s reference to “all diplomatic and legal avenues” suggested that Mexico could keep pressing through formal channels as it seeks accountability.

That matters because deaths in custody can strain cooperation well beyond consular affairs. The dispute touches bilateral ties at a time when migration enforcement, border policy and wider U.S.-Mexico relations already demand close coordination.

What Families and Advocates Have Said

For families, the effect is immediate and personal. The Mexican government has provided financial aid for the repatriation of remains and legal assistance to families seeking to sue the U.S. government for wrongful death or negligence.

Consular involvement can determine how quickly families receive information, how remains are returned and whether relatives can pursue claims. In deaths that occur inside detention, those steps often become the first measure of whether authorities are acting transparently.

Advocacy groups such as the ACLU and Detention Watch Network have criticized detention conditions and access to care. They have reported “abysmal conditions,” including inadequate medical care and overcrowding, which they say contribute to untreated mental-health crises and medical emergencies.

Those concerns go beyond one nationality. But the deaths of 13 Mexican nationals have given Mexico a clear reason to intervene publicly and repeatedly.

The pattern also affects trust in detention oversight and due process protections. When deaths rise and investigations remain open, detainees’ families, advocates and foreign governments often focus on whether the system can police itself.

In this case, Mexican officials have tied their demands to both accountability and non-recurrence. That language reflects a push not only for answers about Pérez Jiménez, but for changes that would prevent similar deaths.

Official Statements and Source Documents

Official documents remain the clearest way to track how the case evolves. Mexico has issued statements through the Mexican Ministry of Foreign Affairs, while ICE has published death-related announcements and other materials in its newsroom.

Readers can also follow broader agency positions through the Department of Homeland Security, which carries background materials and statements tied to immigration enforcement. As investigations continue and officials on both sides issue new statements, those records show where the two governments agree, where they differ, and why Royer Pérez Jiménez’s death has become a test of accountability on both sides of the border.
