Jeremy Richman remembers his daughter Avielle as a fun spirit with "this unbelievable smile that she would just give out to anybody," who was as happy playing dress-up as a fairy at a ball as she was practicing Kung Fu and shooting a bow and arrow outside. Avielle was killed with 19 of her classmates and six educators in the 2012 Sandy Hook Elementary School shooting in Newtown, Connecticut, and in her memory, the Richmans started The Avielle Foundation, which funds research on brain health and causations for violent behaviors.
