How Legacy of a Firefighter Killed on 9/11 Continues to Save Lives 20 Years On

In the early 1990s, FDNY member Terry Farrell saved the life of 5-year-old Chantyl Peterson. The little girl from Nevada had been diagnosed with T-cell lymphoma, a cancer that can be terminal. Farrell donated his bone marrow to the girl, who was able to go on to live a healthy life. The firefighter lost his life on 9/11, but his brother explains how his legacy has lived on and continues to inspire others to save lives.
