On September 15, 1963, 15 year-old Carolyn Mckinstry walked into the sanctuary to hand in Sunday school papers to the office at 16th Street Baptist Church. Within a few steps, she heard a large explosion. A bomb had been ignited. This particular bomb killed four little girls: Cynthia Wesley, Carole Robertson, Addie Mae Collins, and Denise McNair. The bombing not only shook the nation, but reached overseas to the heart of a man named John Petts. He was in Wales, 4,000 miles from the scene of the crime.
