ICE Officer's Fatal Shooting of Colombian Immigrant in Maine Draws Scrutiny of Vetting, Training

An Immigration and Customs Enforcement officer fatally shot Johan Sebastián Durán Guerrero, a 26-year-old Colombian immigrant, in Biddeford, Maine, in a shooting that occurred prior to July 13, 2026. Maine State Police, the state Attorney General's Office, and federal officials are jointly investigating the incident to determine the facts. Governor Janet Mills received a briefing on the shooting on July 13 and subsequently sent a letter to the Maine congressional delegation calling for Congress to immediately reform ICE, stating in her communication that the agency must be fundamentally reformed or abolished. Following the shooting, scrutiny turned to the officer's background and vetting. Reports emerged that the officer's two ex-wives had accused him of abuse. On July 26, Tom Homan, the Trump administration's border czar, told CNN's State of the Union that he did not believe the officer should have cleared ICE's vetting process, and separately indicated that the vetting of the officer was under internal review. Two Democratic lawmakers sent a letter demanding details and records concerning the officer's training, according to a letter obtained by CBS News. As of the most recent reporting, the internal review of the officer's vetting referenced by Homan had not been concluded, and no findings from the joint Maine State Police, Attorney General's Office, and federal investigation into the shooting itself had been publicly released. The specific records and training details sought by congressional Democrats had not yet been provided as of their letter. It remains unresolved what disciplinary or legal consequences, if any, the officer may face, and whether Congress will act on Governor Mills' call for ICE reform.
