Chattanooga Strong: A city mourns, a city heals

Supporters gather for an interfaith vigil at Olivet Baptist Church held in remembrance of victims of the July, 16 shootings on Friday, July 17, 2015, in Chattanooga, Tenn. The vigil was held one day after gunman Mohammad Youssef Abdulazeez shot and killed four U.S. Marines and wounded two others and a Chattanooga police officer at the Naval Operational Support Center on Amnicola Highway shortly after firing into the Armed Forces Career Center on Lee Highway.
