Plot Synopsis

Using re-creations and detective narration to tell the story of a murder case, each one-hour episode of ATL HOMICIDE follows two veteran homicide detectives, David Quinn and Vince Velazquez of Atlanta PD, as they investigate the real-life murder case as if it was in real time. The series opener, "Dark Secrets," focuses on the case of Tereon Grant, a young single mother found murdered in the middle of the night. All signs point to her ex-boyfriend being the killer, but Detectives Quinn and Velazquez dig deeper into the case, uncovering a dark secret that changes everything: Tereon was the victim of a psychopathic killer preying on high class prostitutes.

On Monday, June 17, 2019 at 9pm ET/PT, TV One premiered the second season ATL HOMICIDE, with Detectives Quinn and Velazquez returning to recount their personal experiences solving cases, which include the following stories in the new season: on a hot summer night in early August, two assailants attempt to rob a man's house, who's rumored to have a great deal of cash; when an elderly man who always paid his rent on time, failed to do so, his apartment manager calls in for a welfare check; Demetrius Robbins was a stand-up husband and dedicated father, until one night when the unthinkable happened; and Jimmie Atkins was well-liked by everyone in his neighborhood, but when family and friends don't hear from him for days, suspicions arise.
