“He killed her and tore a hole in our hearts.” Hundreds of colleagues, family and friends filled a concert hall on Long Island Wednesday to mourn the 61-year-old veteran EMS member, World Trade Center first responder and mother who was stabbed to death in a gruesome act of random violence on a Queens sidewalk last week. Alison Russo's family, including her parents, were in the front row at the Tilles Center for Performing Arts in Brookville -- and her father, stalwart in his grief, minced no words. #nbc4ny #fdny
