DOWNTOWN BROOKLYN - A Bay Ridge firefighter met a man on Wednesday whose life he saved by donating bone marrow.

Aaron Faulker, an Iraq War veteran as well as a husband and father, was dealt a major blow in 2013 when he was diagnosed with leukemia. He says he was told he had less than 10 years to live unless he got a bone marrow transplant.

Brooklyn firefighter Michael McCauley donated his bone marrow to Faulker, who until Wednesday was a complete stranger.

McCauley spends his day working as a firefighter for Engine Company 242 in Bay Ridge. He is also on the New York Blood Center's bone marrow donation list and says he wishes more people would get on the list to save lives.

McCauley joined a long list of firefighters who have donated bone marrow through the NYBC. There are more than 8,000 firefighters on the potential donor list, which makes up the largest single group.
