September 11, 2001 - The Years After

Special Agent Thomas Michael Wischerth was assigned to the search and recovery at the World Trade Center site after September 11, 2001. He was 48 years old that fall.

He died on March 26, 2017 - 15 years and 6 months later - of an illness contracted there. He was 63.

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
