Twenty children were killed at their school in Newtown, Conn., on Dec. 14, 2012. Many more have been killed since. In the wake of those deaths, MSNBC began profiling child victims of gun violence. More than 20 families live with the horrific loss, and communities across the country–far from the Connecticut suburbs–continue to grieve children with big dreams. One hoped to become a professional football player, another created a petition to ban puppy mills. One boy could explain in intricate detail the difference in locomotives, another child enjoyed making blueberry pancakes. No president has read their names aloud at a national memorial service, but these children had their own stories to share. Here is a glimpse into the lives of more children who were killed by guns since the tragedy at Sandy Hook Elementary School.
