Maine’s congressional delegation is calling for the Department of Homeland Security to investigate the fatal ICE-involved shooting in Biddeford on Monday.

Senators Angus King and Susan Collins, along with Representatives Chellie Pingree and Jared Golden sent a letter asking for the investigation.

The letter seeks a detailed sequence of events that led to the shooting.

It also asks to what extent DHS will collaborate with state or local agencies in carrying out the investigation.

A 26-year-old Columbian national was shot and killed by ICE Monday during an enforcement operation in which the person shot was not the target of the investigation.

The letter is addressed to DHS Inspector General Joseph V. Cuffari.

“Given the gravity of the situation and the understandable anxiety within the Biddeford community, we urge you to prioritize this investigation,” the letter reads. “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.”
