As of the current Season 22, The First 48 only has three filming locations. Other than Tulsa, it's also filming in Mobile, Alabama with the Mobile Police Department homicide unit, and in Gwinnett County, Georgia with the Gwinnett County Sheriff's Office.

Mobile has been with the series since the last episode of Season 18, while Gwinnett County joined the roster in Season 20, making Tulsa the longest-tenured department on The First 48.

Fans have constantly asked about other favorite locations like New Orleans and Atlanta, but as of now, there are no plans to add another department (new or old) to the show.

And with the success of Tulsa, it's not strictly necessary. The Oklahoma homicide detectives bring more than enough interest to the series with their intriguing cases and admirable policing.

The First 48 airs on Thursdays at 8 p.m. ET on A&E.
