Sandy Hook School Shooting

On December 14, 2012, one of America's most tragic incidents of gun violence took place. A lone gunman, 20-year-old Adam Lanza, broke into Sandy Hook Elementary School in Newtown, Connecticut and murdered 26 people, including 20 children, before killing himself. It is the second deadliest school shooting in the United States. The tragedy reignited the nation's long-standing debate over gun control and a ban on assault weapons.
