The First 48 Presents: Homicide Squad Atlanta

A&E | 9:00 pm

Frustrated by the lack of progress in finding leads in the brutal murder of Bridget Shiel, Detective Lowe organizes a vigil on the first anniversary of the crime in a bid to give her family some closure, plus — with any luck — to turn up something helpful to the investigation, in the new episode "Hot Sun, Cold Blood." A tip leads the detectives on a wild chase, but the best evidence they have is some DNA they haven’t been able to match.
