Incident
Location: New York Incident Date: Tuesday, September 11, 2001 Weapon: Aircraft; Passenger jet Offender: 19 suicide attackers
Deputy U.S. Marshal Kenneth Doyle died as the result of cancer that he developed following his assignment to assist with search and rescue efforts and to escort other government officials around the World Trade Center site immediately following the 9/11 Terrorist Attacks.
Deputy Marshal Doyle was a U.S. Navy veteran and had served with the United States Marshals Service for 20-1/2 years.
September 11, 2001 - The Years After
Deputy U.S. Marshal Kenneth J. Doyle was assigned to the search and recovery at the World Trade Center site after September 11, 2001. He was 50 years old that fall.
He died on July 26, 2017 - 15 years and 10 months later - of an illness contracted there. He was 65.
He is one of 599 officers honored here, and one of 3 at United States Department of Justice - United States Marshals Service.
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 and four children.
