Roll of Honor
Incident
Lieutenant Michael Shea 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.
Lieutenant Shea had served with the Nassau County Police Department for 26 years and had previously served with the New York City Police Department for five years.
September 11, 2001 - The Years After
Lieutenant Michael P. Shea 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 April 1, 2017 - 15 years and 6 months later - of an illness contracted there. He was 52.
He is one of 599 officers honored here, and one of 14 at Nassau County 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, two sisters, brother, and nieces and nephews.
