U.S. Immigration and Customs Enforcement agents have been told to end most vehicle stops after this week's deadly shooting in Biddeford.

That policy change, according to Fox News, does not include pursuits targeting people with violent criminal histories wanted for deportation and is not permanent.

It comes on the heels of fatal shootings that claimed the lives of 52-year-old construction worker Lorenzo Araujo in Texas last week and 26-year-old Johan Sebastián Duran Guerrero on Monday morning in Biddeford.

U.S. Sen. Susan Collins, R- Maine, said in a Tuesday statement that she called on Homeland Security Secretary Markwayne Mullin, who oversees ICE, among other agencies, to cease all "non-urgent" vehicle stops, saying that Guerrero's death, while still under investigation, raised "sufficient critical questions."

An ICE spokesperson declined to confirm the policy shift in a statement to the Bangor Daily News.

"We are always evaluating our procedures to keep our officers safe and criminals off our streets. We will not disclose or discuss law enforcement tactics," the spokesperson said in an email.

Guerrero was shot and killed about 7 a.m. at the intersection of Pool and Hill streets, where he encountered two or three agents with ICE's Enforcement and Removal Operations division.

Questions continue to swirl around what took place between Guerrero and the agents before Monday's shooting.

Four or five shots were fired when the Colombian allegedly tried to flee from agents, who haven't been publicly identified but have been placed on administrative leave.

In a Monday evening statement, an ICE spokesperson said that Guerrero was in the country illegally and had a final removal order against him. But Mullin, who previously suggested Guerrero had "weaponized" his white Kia, told independent U.S. Sen. Angus King that Guerrero wasn't actually the target of the agents' administrative warrant.

Two immigrant advocacy groups here, Maine Immigrants' Rights Coalition and Presente! Maine, said in a joint statement that Guerrero, who leaves behind a wife and young daughter, had authorization to work in the United States and had been issued a Social Security number.

The ICE agents weren't equipped with body cameras, for which Congress approved $20 million in funding, meaning there's apparently no direct video evidence of what happened between Guerrero and them in the moments before the shooting.

Several federal, state and local law enforcement agencies are participating in the investigation, which the Colombian embassy said it will be monitoring as it stays in touch with Guerrero's family here.

In a Tuesday letter to Homeland Security Inspector General Joseph Cuffari, Maine's congressional delegation called for a "comprehensive, transparent, and expedited investigation" into Guerrero's death.

"Given the gravity of the situation and the understandable anxiety within the Biddeford community, we urge you to prioritize this investigation," Collins, King and Democratic U.S. Reps. Chellie Pingree and Jared Golden wrote. "Timely and factual answers will be critical to providing closure for the grieving community and ensuring that federal law enforcement operations are conducted safely, lawfully, and in a manner that respects public safety."

This may be at least the 11th fatal shooting involving ICE agents since President Donald Trump's second inauguration. That doesn't include deaths of those in the agency's custody. As of July 6, at least 21 people have died in immigration detention centers in 2026, on top of 33 who died last year, according to the National Immigration Project.

Earlier this year, Maine became the latest state to see a surge in ICE agents as part of the Trump administration's Operation Catch of the Day. That surge was cut short amid a nationwide pushback against the agency's tactics following the fatal shootings of two protesters in Minneapolis.

Of the nearly 200 detained in Maine during the January ICE surge, only 11 had criminal convictions, undercutting the Trump administration's claim that it was targeting the "worst of the worst."
