Roll of Honor
William C. Sheldon
Incident
Location: New York Incident Date: Tuesday, September 11, 2001 Weapon: Aircraft; Passenger jet Offender: 19 suicide attackers
Special Agent Bill Sheldon died as the result of cancer he developed as a direct result of participating in rescue and recovery efforts at the World Trade Center site following the 9/11 Terrorist Attacks.
Agent Sheldon assisted with directing people away from the towers on the day of the attack. He was then exposed to toxic debris while assisting with the search and recovery efforts at Ground Zero in the weeks following the attack. He and two other members of his 5-person ATF team were eventually diagnosed with cancer that was determined to be a result of their exposure to the toxic debris.
His health continued to deteriorate until he passed away on March 2nd, 2015.
Special Agent Sheldon was a U.S. Army combat veteran and had served with ATF for 22 years.
September 11, 2001 - The Years After
Special Agent William C. Sheldon was assigned to the search and recovery at the World Trade Center site after September 11, 2001. He was 34 years old that fall.
He died on March 2, 2015 - 13 years and 5 months later - of an illness contracted there. He was 47.
He is one of 599 officers honored here.
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 two young children.
