Addie Mae Collins was born in Birmingham, Alabama, on April 18, 1949. She attended the 16th Street Baptist Church with her parents, Julius and Alice, as well as her six siblings. On the morning of Sunday, September 15, 1963, 14-year-old Collins was in the church basement room with a group of other children. At 10:22 a.m., a bomb exploded under the steps of the church. Collins was killed in the blast along with Denise McNair, 11, and Carole Robertson and Cynthia Wesley, both 14. In addition to the four fatalities, more than 20 people were injured. One of these was Collins' younger sister, Sarah, who lost an eye and sustained other serious injuries. In 1977, a 73-year-old Chambliss was convicted of the murder of Collins and sentenced to life in prison. Two other perpetrators—Thomas Blanton Jr. and Bobby Frank Cherry—were convicted in 2001 and 2002, respectively. A fourth suspect, Herman Frank Cash, died in 1994, before he could be charged.
