Twenty-five years after 9/11, we're remembering the nearly 3,000 people who lost their lives that day — including 39-year-old Frank Doyle, who was in the South Tower. His wife, Montrealer Kimmy Chedel, is joining us live from Ground Zero this morning, 25 years after she lost Frank. She's spent those years raising their children and turning her grief into a mission of helping others. She spoke to Andrew Carter.
