BROOKLYN - The son of an FDNY firefighter is in need of a bone marrow transplant after being diagnosed with a rare disease.

Tom Hogan’s son, Tim, is suffering from aplastic anemia, a rare bone marrow failure disease. If the 2-year-old boy can’t find a donor, he is at risk for heart failure.

A bone marrow donor drive in Red Hook has already attracted neighbors and borough residents, including actor Steve Buscemi – a Brooklyn native and former FDNY firefighter.

“I met Owen's dad and we're already brothers,” Buscemi told News 12.

The testing process consists of filling out a form and a mouth swab.

The donor drive will take place all week at the Friends of Firefighters building at 199 Van Brunt St.
