A 31-year-old Mexican immigrant named Alberto Castañeda Mondragón suffered severe skull fractures and brain hemorrhaging while in the custody of Immigration and Customs Enforcement (ICE) agents in Minnesota. Hospital staff members immediately doubted ICE's claim that Castañeda Mondragón had tried to flee and "purposefully ran headfirst into a brick wall," saying his injuries were inconsistent with that account. The incident has contributed to mounting friction between ICE officers and healthcare workers at the Hennepin County Medical Center in Minneapolis.

Why it matters

This case highlights ongoing tensions between immigration enforcement and the medical community, with healthcare workers accusing ICE agents of using aggressive tactics, defying hospital policies, and intimidating staff. It also raises questions about the treatment of immigrants in federal custody and the transparency around injuries sustained by detainees.

The details

According to court documents, Castañeda Mondragón suffered at least eight skull fractures and life-threatening brain hemorrhages just hours after his arrest near a St. Paul shopping center on January 8. ICE's account of how he was injured evolved, with at least one officer initially telling hospital staff that Castañeda Mondragón "got his (expletive) rocked." Hospital staff determined his injuries could not have resulted from running into a wall as ICE claimed. The situation escalated when ICE insisted on shackling Castañeda Mondragón to his hospital bed, prompting a confrontation with staff.

  • Castañeda Mondragón was arrested on January 8, 2026.
  • He was taken to the hospital emergency room in Edina about 4 hours after his arrest.
  • Castañeda Mondragón was then transferred to Hennepin County Medical Center in Minneapolis.
  • On January 16, a court filing described his condition as "minimally responsive and communicative, disoriented and heavily sedated."
  • On January 28, a U.S. District Court judge ordered Castañeda Mondragón released from ICE custody.

What they’re saying

“It was laughable, if there was something to laugh about. There was no way this person ran headfirst into a wall.”

— Unnamed nurse, Nurse at Hennepin County Medical Center

“We were basically trying to explain to ICE that this is how someone with a traumatic brain injury is — they're impulsive. We didn't think he was making a run for the door.”

“He still doesn't remember things that happened. I think (he remembers) 20% of the 100% he had. It's sad that instead of having good memories of the United States, you're left with a bad taste in your mouth about that country because they're treating them like animals.”
