Homicide detectives David Quinn and Vince Velazquez are veterans of the Atlanta Police Department. They are sitting down to share some of the grittiest stories of their careers. Quinn and Velazquez recall these cases and talk about their personal experiences while solving the crimes. They have tackled hundreds of cold cases together, with anything from murder to everyday crime, and they try to bring these criminals to justice and give peace to the victims' families. "Through each compelling case, audiences will feel like what they are watching unfold is happening in real time," says Tia A. Smith, the senior director of original programming and production.
