NEW YORK (CBSNewYork) – The FDNY promoted nearly 100 of its members Friday.

Among them were two brothers with a special reason for joining the force. 

Sean and William Heeran lost their brother, Charlie, during the September 11th terror attacks. He was 23 years old and had been working at Cantor Fitzgerald.

The Heeran brothers said his death inspired them to join the department.

Their father was also a firefighter.
