A Killer in the Family

In New Orleans, a double-shooting on Bourbon Street leaves only one survivor and the hope he can name the suspect. In Birmingham, when a young man and his girlfriend are shot in his home, only she survives. Detectives must determine if the suspects she named are indeed the killers. And in Gwinnett County, when a man stabbed more than 20 times survives, detectives must await his recovery to get answers.
