Cameras have been following Gwinnett County homicide detectives for more than a year; soon, you'll be able to see them at work in the first episode of A&E's "First 48."

The documentary crime show follows police agencies across the countries in the first 48 hours of a homicide investigation. That time frame is considered critical in homicide investigations.

The first episode featuring Gwinnett County police is scheduled to air Thursday, Feb. 7. It features a fatal shooting that occurred at the Midnight Blu Cafe nightclub in Norcross.

Gunfire was exchanged between multiple people outside Midnight Blu Cafe after an argument escalated early on the morning of Oct. 1, 2017. More than 80 shots were fired, killing 19-year-old Domiquo Riley and injuring another clubgoer. Security guard Christopher Parker, 42, has been charged with murder in connection with Riley's death. Oshay Howard, 20, and Kyese Patrick, 21, have both been charged with aggravated assault. All three are being held in the Gwinnett County Detention Center, awaiting trial.

More episodes featuring Gwinnett County homicide cases are expected to follow, a department spokesperson said. The show airs Thursdays at 8 p.m. on A&E.
