Incident

Location: New York Incident Date: Tuesday, September 11, 2001 Weapon: Aircraft; Passenger jet Offender: 19 suicide attackers

Special Agent Loius Aguirre died as the result of cancer that he developed following his assignment to the search and recovery efforts at the World Trade Center site following the 9/11 Terrorist Attacks.

Special Agent Aguirre was a U.S. Army veteran. He had served with the United States Immigration and Customs Enforcement - Homeland Security Investigations and the legacy United States Department of Justice - Immigration and Naturalization Service for 19 years. He had previously served with the Federal Bureau of Prisons.

September 11, 2001 - The Years After

Special Agent Louis Henry Aguirre was assigned to the search and recovery at the World Trade Center site after September 11, 2001. He was 37 years old that fall.

He died on November 27, 2020 - 19 years and 2 months later - of an illness contracted there. He was 56.

He is one of 599 officers honored here, and one of 7 at United States Department of Homeland Security - Immigration and Customs Enforcement - Homeland Security Investigations.

The most recent of these deaths was October 24, 2025.

Officers who worked the search, rescue, and recovery at the World Trade Center site breathed contaminated air for weeks and months afterward. Many developed cancers and respiratory disease, and they have gone on dying of it ever since.

Seventy-two officers were killed on the morning itself. Hundreds more have died in the years that followed. They are honored here together, because the same attack killed them all. With some it simply took longer.

Survivors

He is survived by his wife.
