ST. JAMES, N.Y. (AP) — Nearly 15 years after the Sept. 11 terror attacks, a funeral is being held for a New York City fire chief who died in the World Trade Center collapse.
The remains of Safety Battalion Chief Lawrence Stack were never found. But his family recently discovered two vials of blood that he had donated during a bone marrow drive for a child with cancer.
On Friday, the blood vials will be buried at Long Island's Calverton National Cemetery following a funeral Mass.
Stack's service in the Fire Department of New York was part of a family tradition.
Two sons are firefighters. His father was a 38-year veteran of the FDNY and his brother served 26 years.
