A 26-year-old delivery driver named Joan Sebastian Guerrero left his Biddeford, Maine home on Monday morning to do his job. Within minutes, he was dead. A federal immigration agent shot him through the window of his own car while his young daughter, still wearing her pajamas, watched from nearby.
The Department of Homeland Security initially claimed the shooting was a standard self-defense reaction to an "illegal alien" who tried to weaponize his vehicle during a targeted operation. But hours later, that official narrative completely fell apart.
It turns out federal authorities killed the wrong man.
Anatomy of a Wrongful Operation
The tragic sequence of events started around 7:00 AM on July 13, 2026, at the intersection of Pool and Hill streets. Enforcement and Removal Operations agents from ICE were staking out an apartment building, waiting for a completely different person who held a final order of removal. When Guerrero got into his white sedan, agents moved in.
Eyewitnesses reported seeing an unmarked Ford Explorer flash its lights and ram into Guerrero’s sedan. Agents in green tactical vests jumped out with their weapons drawn, screaming at him to get out. Terrified, Guerrero tried to drive away. An agent opened fire, pumping four shots into the vehicle.
The agency’s first instinct was damage control. They put out a statement alleging they attempted a vehicle stop, the driver fled, and an officer fired out of "fear for public safety." They also labeled Guerrero an "illegal alien."
They omitted a massive detail. Guerrero was not the guy they were looking for. Maine Senator Angus King later confirmed that DHS Secretary Markwayne Mullin admitted to his office that Guerrero was never the intended target of the warrant.
Who Was Joan Sebastian Guerrero?
Guerrero moved from Colombia to southern Maine to build a quiet, stable life for his family. Local immigrant advocacy groups, including the Maine Immigrants’ Rights Coalition and Presente! Maine, quickly verified that he was legally authorized to live and work in the United States, possessing a valid Social Security number. He spent his days driving for DoorDash to support his wife and their three-year-old daughter.
Neighbors knew him as a dedicated, hardworking father. When agents pulled his bleeding body from the front seat of his car, a witness heard Guerrero gasp his final words: "I tried to stop."
The Deadly Pattern of Vehicle Stops
This isn't an isolated mistake. Guerrero is the 11th person shot and killed by federal immigration officers since January 2025. Even more troubling, he is the fifth person killed under nearly identical circumstances—while inside a vehicle. Just six days before this incident, ICE agents in Houston shot and killed Lorenzo Salgado Araujo while searching for someone else. Salgado, too, was simply driving to work.
Internal anxiety over these recurring fatalities has forced a sudden policy pivot. Facing intense public backlash and video footage that contradicts initial agent statements, ICE high command ordered a nationwide freeze on most vehicle stops. Moving forward, agents are temporarily banned from pulling over cars until they undergo new training regarding high-risk vehicle encounters.
What Happens Next
The Maine State Police and the state's Attorney General, Aaron Frey, have taken over the local investigation. Because the federal agents involved were not wearing body cameras, investigators are relying heavily on local security footage and witness mobile phone videos to piece together the exact timeline.
Local leaders are demanding immediate systemic change. Biddeford Mayor Liam LaFountain and state lawmakers have openly called for a complete halt to ICE operations within the city limits.
If you want to track the accountability process or support the family, here are the direct avenues for action:
- Monitor Local Oversight Updates: Watch the official press portal of the Maine Attorney General’s Office for updates on the state-level criminal review of the shooting officer.
- Support Community Advocacy: Connect with the Maine Immigrants’ Rights Coalition or Presente! Maine to participate in local vigils, legal defense funds, and ongoing policy demands for municipal non-cooperation with federal immigration raids.
