The book – Keep Kids Safe: Don’t Let Our Schools Become Killing Zones – details the path that a memorial plaque took from Thomas Jefferson High School in Brooklyn and eventually arriving at Sandy Hook Elementary School. Thomas Jefferson, which has now closed, was in a touch Brooklyn neighborhood and also the scene of two separate school shootings which claimed three lives. The last slaying was on February 26, 1992 when a 15-year-old boy fatally shot two students after getting into a feud with them. When the mass shooting occurred at Columbine High School former students from the New York felt compelled to travel to Littleton, Colorado to provide comfort to students and help those who survived the ordeal to heal. The plaque presented to Columbine remained at the high school until tragedy struck a school in Red Lake, Minnesota when a 15-year-old boy killed five students, a teacher and a security guard. He murdered his grandfather and another person before embarking on the killing spree at the school. Students from Columbine thought it was necessary to take the plaque to the remote First Nation community to help those recover from the violence. They also hoped it would be the last stop the memorial plaque would ever make. However, during this past Christmas period a group of former and current students from Red Lake Senior High School made the 1,492 mile journey to Newtown, Connecticut to help students from Sandy Hook Elementary School heal from the tragedy they endured. The trail the plaque took and those who made it their mission to help others heal are outlined in the book, which also makes mention of a watercolor – Happier Days – which was delivered to Northern Illinois University to provide comfort after a gunman killed six people and wounded 21 other on February 14, 2008. It was from residents of Nickel Mines, an Amish community in Pennsylvania, where five girls were murdered in the classroom of a one room schoolhouse on October 2, 2006.
