Trump administration officials told Immigration and Customs Enforcement officers to suspend most vehicle stops after two deadly shootings within a week, people familiar with the decision said Tuesday.

The policy change came after an ICE officer shot and killed a Colombian driver Monday in Maine and a week after one shot and killed a motorist in Houston, renewing criticism of the agency’s enforcement tactics that were widely condemned last winter after the killings of Alex Pretti and Renee Good in Minnesota.

The suspension allows room for exceptions when executing a criminal warrant or working with partner agencies, according to a person who spoke Tuesday on condition of anonymity to discuss sensitive law enforcement operations. Matthew Felling, a spokesperson for Maine Sen. Angus King, said the senator’s office was also told by the Department of Homeland Security that ICE was suspending vehicle stops.

Hundreds of people in Maine protested Tuesday over the fatal shooting of Johan Sebastián Durán Guerrero, a 26-year-old Colombian national.

DHS said Monday that an officer, “fearing for public safety,” shot and killed Durán Guerrero while officers were watching the home of someone they believed was in the U.S. illegally and facing a final order of removal from the country. It said in a post on X that when ICE tried to stop a car driven by someone who came from the home, the vehicle attempted to flee and the officer fired.

That was a shift from how King earlier described the encounter, when he said Homeland Security Secretary Markwayne Mullin told him the officer opened fire after the man tried to use his vehicle as a weapon. King said Mullin told him the officers were trying to serve an arrest warrant, but not for the man who was shot.

DHS, which oversees ICE, didn’t respond to an email seeking clarity on what led to the shooting.
