David Michael Brouillette, a 37-year-old ICE agent, has been identified as the individual who shot and killed 26-year-old Johan Sebastián Durán Guerrero in Biddeford. Brouillette's ex-wife, Ashley Brouillette, stated that he admitted to the shooting and claimed it was justified, alleging that Guerrero attempted to hit him with a car. She expressed concerns about his mental health and reported past abusive behavior during their relationship.
The incident occurred while ICE agents were conducting surveillance in the area. Guerrero was living in Biddeford with his partner and young daughter at the time of the shooting. The Department of Homeland Security has not publicly identified Brouillette or the other agents involved in similar incidents. A witness confirmed seeing an agent matching Brouillette's description at the scene.
Brouillette has a history of employment in law enforcement and public safety in Maine, including a position with the Department of Veterans Affairs. He is a U.S. Army veteran who served from 2010 to 2015 and has received disability benefits. His work history includes brief tenures at various agencies, with reports of conflicts in some positions. This shooting marks him as the second federal immigration officer from Maine involved in a shooting during enforcement operations.
