Special Agent Robert C. Castioni Jr. was assigned to the search and recovery at the World Trade Center site after September 11, 2001. He was 46 years old that fall.

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, two daughters, a son, three brothers, a sister, and three grandchildren.
