FBI Investigates ICE Arrest After Mexican Man Suffers Eight Skull Fractures
On January 8, 2026, Alberto Castañeda Mondragón was arrested by Immigration and Customs Enforcement (ICE) officers in a St. Paul, Minnesota shopping center parking lot. What happened next landed him in the intensive care unit with eight skull fractures, brain hemorrhaging, and fragmented memory.
Now the FBI and St. Paul Police Department are investigating. They want to know what really caused injuries so severe that doctors say they couldn't have happened the way ICE claims.
For immigrants living in the United States, this case raises serious questions about what can happen during an ICE arrest and whether officers are being held accountable when things go wrong.
What Happened During the ICE Arrest in Minnesota?
According to NBC News reporting, ICE arrested Castañeda Mondragón in a shopping center parking lot in St. Paul. He's a 31-year-old Mexican citizen who ICE says overstayed his work visa.
Castañeda Mondragón told the Associated Press that ICE officers "started beating me right away when they arrested me." He says they pulled him from a vehicle, threw him to the ground, and hit him repeatedly in the head with a steel baton. He called the officers "racist."
But ICE tells a completely different story. The agency says Castañeda Mondragón tried to run away while he was already in handcuffs. According to ICE, he "fell and hit his head against a concrete wall" while running toward a main highway.
Hospital staff who treated him don't buy ICE's version. They told reporters that a simple fall couldn't cause the kind of injuries he had. A CT scan showed fractures on the front, back, and both sides of his skull. One doctor said these injuries were "inconsistent with a fall."
Why Are the FBI and Police Getting Involved Now?
Last week, investigators from both the FBI and St. Paul Police Department went to the shopping center where the arrest happened. They asked local businesses for surveillance camera footage.
But there's a problem. More than a month passed between the arrest and when investigators asked for the video. Some businesses told reporters their cameras didn't capture the arrest. Others said their footage had already been automatically deleted after 30 days.
Johnny Ratana owns an Asian grocery store that faces the parking lot where ICE arrested Castañeda Mondragón. He said St. Paul police came twice to ask for video. The second time, they brought a data technician to try to recover the deleted footage. The FBI also visited him looking for the same video.
The delay happened partly because St. Paul police said they couldn't investigate until Castañeda Mondragón filed an official police report. But he was in the hospital for weeks and wasn't sure about his immigration status. He finally gave his statement at the Mexican consulate a week ago.
This isn't the first time ICE has faced serious questions in Minnesota. Federal prosecutors recently dropped charges against two Venezuelan men after video showed ICE officers may have lied under oath about being attacked with a snow shovel and broom handle. The FBI is also investigating the fatal shooting of Alex Pretti by ICE officers on January 24.
What Is ICE Saying About the Skull Fractures?
The Department of Homeland Security refused to discuss Castañeda Mondragón's injuries for weeks. They didn't answer questions about whether ICE officers were wearing body cameras or if they recorded the arrest.
Last week, Tricia McLaughlin (the department's assistant secretary for public affairs) defended ICE's version of events. She said ICE was conducting "a targeted enforcement operation" to arrest Castañeda Mondragón because he overstayed his visa. She repeated that he hurt himself trying to escape while handcuffed.
But ICE's own court filing from January 20 contradicts this. In that document, ICE said officers only found out Castañeda Mondragón overstayed his visa after they arrested him. So it couldn't have been a "targeted operation" if they didn't know about the visa problem beforehand.
ICE hasn't explained which version is true. And they still haven't said whether the arrest was recorded on body cameras.
What Do His Injuries Really Mean?
Medical professionals who treated Castañeda Mondragón were clear: his injuries are extremely serious and don't match ICE's story.
He suffered eight skull fractures. That means his skull broke in eight different places. The fractures were on the front of his head, the back, and both sides. He also had brain hemorrhaging (bleeding inside his brain). His memory was fragmented when doctors examined him.
A fall, even a bad one, typically causes injury to one part of the head where it hits the ground. Injuries to the front, back, and both sides suggest multiple impacts from different directions. That's why doctors told reporters a single fall against a wall couldn't explain what they saw.
This kind of injury pattern is more consistent with being hit multiple times, which is exactly what Castañeda Mondragón says happened.
What Should You Do Now?
If you're an immigrant in the United States, this case is a reminder that you have rights even during an ICE arrest. Here's what you should know:
1. Know your rights during an ICE encounter. You have the right to remain silent. You don't have to answer questions about where you were born or how you entered the United States. You can say "I want to speak to a lawyer" and nothing else. If ICE comes to your home, you don't have to open the door unless they have a warrant signed by a judge (not just an ICE warrant).
2. Document everything if you or someone you know is arrested. If ICE arrests you or a family member, write down or record everything you can remember: the officers' names or badge numbers, what they said, what happened, any injuries, witnesses who saw what happened. Take photos of injuries as soon as possible. Get medical attention right away if you're hurt, and make sure doctors write down all your injuries in your medical records.
3. Report serious incidents and get help. If you believe ICE officers hurt you or violated your rights, you can file a complaint with the Department of Homeland Security Office of Inspector General. You can also contact local police (though they may not always investigate federal officers). Reach out to immigrant rights organizations in your area. Groups like the ACLU, immigrant legal services, and community organizations can help you understand your options. Contact your country's consulate if you're not a U.S. citizen - they may be able to help.
4. Be prepared and have a plan. Keep important documents (passport, visa papers, proof of how long you've been in the U.S.) in a safe place where family can find them. Have a lawyer's phone number saved in your phone and written down at home. Make a plan with your family about what to do if ICE arrests someone. Know who will take care of your children, who has access to your bank accounts, and how to reach your lawyer.
Frequently Asked Questions
Can ICE officers use force during an arrest?
Yes, ICE officers are allowed to use reasonable force to make an arrest, just like other law enforcement. But the force has to be reasonable for the situation. Beating someone in the head with a baton while they're already in handcuffs would not be considered reasonable force. If ICE officers use excessive force (more than necessary), that's illegal and they can be investigated and charged with crimes.
What should I do if ICE injures me during an arrest?
Get medical help immediately and make sure all your injuries are documented by doctors. Take photos of your injuries if you can. Write down everything you remember about what happened as soon as possible. File a complaint with the Department of Homeland Security Office of Inspector General and contact an immigration lawyer right away. You may also be able to file a civil lawsuit against the officers who hurt you.
Do ICE officers wear body cameras?
Some ICE officers wear body cameras, but not all of them. ICE has been slowly rolling out body cameras, but the agency doesn't have to tell you if they're recording. If you're arrested by ICE and think you were mistreated, your lawyer can request any video footage through a legal process called discovery. The government has to provide it if it exists.
Can local police investigate federal ICE officers?
Yes, local police can investigate federal officers if they believe a crime was committed under state law. Assault and battery are crimes under Minnesota law (and most state laws), even if the person who committed them works for the federal government. However, investigating federal officers can be complicated, and local police sometimes wait for federal agencies like the FBI to take the lead.
What happens to Alberto Castañeda Mondragón now?
According to reports, ICE has told him to come to their main detention facility in Minneapolis on February 23, 2026. When immigrants are ordered to report to ICE, there's a real risk they'll be detained and deported, even if they're the victim of a crime or part of an ongoing investigation. His lawyers will likely try to prevent his deportation while the investigations continue, but his immigration status remains uncertain.
