Incident

Lieutenant Brian Mohamed died from illnesses caused by inhaling toxic materials while partaking in the rescue and recovery efforts at the World Trade Center site, following the 9/11 terrorist attacks.

Lieutenant Mohamed was a U.S. Marine Corps veteran and had served with the New York City Police Department for 17 years. He was assigned to the 20th Precinct in Manhattan.

September 11, 2001 - The Years After

Lieutenant Brian Sean Mohamed was assigned to the search and recovery at the World Trade Center site after September 11, 2001. He was 36 years old that fall.

He died on March 25, 2009 - 7 years and 6 months later - of an illness contracted there. He was 43.

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 and child.
