Immigration and Customs Enforcement has directed agents to halt most traffic stops and will expand body camera use after federal agents fatally shot two people within one week, raising questions about operational protocols during immigration enforcement operations. Neither Lorenzo Salgado Araujo in Houston nor Joan Sebastian Durán Guerrero in Biddeford, Maine, was the target of the operations that resulted in their deaths, sources confirmed.
President Donald Trump's border czar, Tom Homan, characterized the change in traffic stops as a "short pause" rather than a broader administration policy change. The distinction matters. ICE maintains that its enforcement operations remain essential to national security and public safety, even as the agency reviews procedures following the incidents.
The Maine Incident
Durán Guerrero, a 26-year-old from Colombia, was killed Monday morning in Biddeford, Maine's sixth-largest city on the Atlantic Coast. He'd been authorized to work in the US and had been issued a Social Security number, according to the Maine Immigrants' Rights Coalition. Surveillance footage obtained by The Associated Press shows a white sedan, believed to be Durán Guerrero on his way to work, driving in circles near an intersection before an unmarked vehicle blocks its path.
Daniel Boucher, who lives near the scene, told CNN he looked outside after hearing gunshots and saw federal agents pull Durán Guerrero's body from the sedan. The Department of Homeland Security said the ICE officer opened fire after "fearing for public safety" as Durán Guerrero "attempted to flee the scene" in his vehicle. DHS hasn't provided details on why the officer believed Durán Guerrero posed a threat. The officer involved "has nearly a decade of federal law enforcement experience with required training," ICE said.
Durán Guerrero's neighbor said the young man, who was headed to work when the shooting happened, lived with his partner and their 3-year-old daughter. "He was a good person," his neighbor told CNN.
The Houston Case
Salgado Araujo, 52, was driving to work with three other construction crew members when unmarked vehicles carrying federal agents began following his van, his family said. DHS said Salgado Araujo rammed into a law enforcement vehicle and refused to follow several verbal commands before an ICE agent fired his weapon in self-defense. The agency said he attempted to evade arrest during the "targeted operation," though a source with preliminary details about the incident said he wasn't the target of the enforcement action.
Two men who were with Salgado Araujo disputed the government's account. They told attorney Hugo Balderas-Ibarra and Rep. Sylvia Garcia that the agents' vehicles bumped into them and then swayed into the van, forcing them to stop. The agents never identified themselves, the men said. Salgado Araujo's brother, Victor, who was in the van when the shooting happened, told Texas immigration attorney Ruby Powers that during the incident, an unidentified person approached the passenger side window, said, "Stop," and immediately fired a weapon, striking Salgado Araujo.
The three other men who were with Salgado Araujo were detained. The Mexican consulate said ICE granted permission for Victor Salgado to attend his brother's funeral Thursday. Balderas-Ibarra said he secured U Visa certifications for all three men that will prevent them from being deported.
Multiple Investigations Underway
In Maine, local officials have asked for a full and impartial probe. The Maine Attorney General is investigating the shooting alongside local and federal authorities. Homeland Security Secretary Markwayne Mullin told Sen. Susan Collins of Maine that the agency's Office of Inspector General's Boston field office has since taken over the investigation.
In Houston, the DHS' Office of Inspector General now leads an investigation into the shooting, according to ICE. The FBI's Houston field office is investigating the alleged assault on a federal law enforcement officer. Harris County District Attorney Sean Teare's office has also launched its own investigation into the killing of Salgado Araujo. The Houston Police Department has asked the Texas Department of Public Safety to conduct an investigation, saying doing so "will ensure it is independent and transparent."
Teare said Monday that his office has issued nearly 20 subpoenas for evidence and witness testimony and that federal officials aren't sharing evidence with investigators. That lack of coordination raises concerns about accountability mechanisms when federal enforcement operations result in civilian deaths.
Amid the other deaths, Homeland Security Investigations, part of ICE, and the Florida Highway Patrol are also investigating an incident from Tuesday morning where a Mexican national fleeing from federal agents in St. Augustine was struck and killed by a tractor trailer.
Why This Matters:
These incidents expose fundamental tensions between aggressive immigration enforcement and operational accountability. ICE agents operate under significant pressure to execute removal operations, but the deaths of individuals who weren't enforcement targets suggest procedural breakdowns that compromise both public safety and the rule of law. The temporary pause on traffic stops acknowledges this reality without addressing whether current protocols adequately balance enforcement authority with civilian protection. Multiple investigations spanning state, local, and federal jurisdictions reflect fragmented oversight of federal law enforcement operations. District Attorney Teare's complaint that federal officials aren't sharing evidence with local investigators highlights coordination failures that could prevent accountability. For immigration enforcement to maintain public legitimacy and legal authority, operational transparency isn't optional—it's essential to demonstrating that federal agents operate within constitutional constraints, even during high-priority enforcement operations.
