Incident

Corporal Harvey Snook passed away on January 14th, 2016, as the result of cancer contracted while working in the recovery efforts at the Pentagon following the terrorist attack on September 11th, 2001.

He was working on patrol when he responded to the Pentagon after American Airlines Flight 77 struck the Pentagon at 9:38 am. He remained working at the site for the following week collecting evidence and the remains of victims. He was diagnosed with cancer related to the recovery efforts on September 9th, 2014.

Corporal Snook was a U.S. Army veteran and had served with the Arlington County Police Department for 27 years.

September 11, 2001 - The Years After

Corporal Harvey Snook, III was assigned to the search and recovery at the World Trade Center site after September 11, 2001. He was 35 years old that fall.

He died on January 14, 2016 - 14 years and 4 months later - of an illness contracted there. He was 49.

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 mother.
