September 11, 2001 - The Years After
Supervisory Special Agent Dennis M. Wagner Jr. 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 March 5, 2025 - 23 years and 5 months later - of an illness contracted there. He was 60.
He is one of 599 officers honored here, and one of 19 at United States Department of Justice - Federal Bureau of Investigation.
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 was survived by his wife, daughter, and son.
