Incident

Police Officer Dave Guevara died as the result of cancer that he developed following his assignment to the search and recovery efforts at the World Trade Center site following the 9/11 Terrorist Attacks.

Officer Guevara had served with the NYPD for 21 years.

September 11, 2001 - The Years After

Police Officer Dave E. Guevara was assigned to the search and recovery at the World Trade Center site after September 11, 2001. He was 30 years old that fall.

He died on April 7, 2017 - 15 years and 6 months later - of an illness contracted there. He was 45.

He is one of 600 officers honored here, and one of 451 at New York City Police Department.

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.
