Kelly Siegler and the Cold Justice team are taking on another batch of unsolved cases.

At the 2023 CrimeCon, the former Harris County prosecutor and executive producer Zak Cordova confirmed that they’re hard at work on yet another season of the beloved true crime series. A premiere date has yet to be scheduled, but Siegler estimated the series will debut on Oxygen in 2024. 

In the meantime, Siegler and executive producer Andrew Nock are preparing for the release of Oxygen‘s Prosecuting Evil with Kelly Siegler, which will explore cases from Siegler’s career as a prosecutor in Texas. It will chronicle all the steps that have to be taken before and after a trial, and feature interviews with those involved in the cases, including family members of the victim, prosecutors, and investigators.  

“We’ve never gotten to see that on Cold Justice before, the actual trial part. So I think they’re gonna go hand in hand,” Siegler shared.

The murder of Texas man Jeffrey Wright is one of the cases to be highlighted in Prosecuting Evil, in addition to the murders of Jennifer Ertman and Elizabeth Peña. Siegler saw both cases through to the very end, forging bonds with the victims’ families in the process.

And Siegler and Cordova hope to one day give viewers a glimpse of a trial in which Cold Justice assisted law enforcement. But, as the old saying goes, the wheels of justice turn slowly. 

“It takes a long time for updates to happen in the criminal justice system. A lot of the cases resulting in arrest, they still haven’t gone to trial. So the updates aren’t as frequent as you would think because that’s the real world,” Siegler said.

The other difficult part is getting permission from judges to film a trial process. Filming may be prohibited for a myriad of reasons, but the primary explanation is that a judge needs to ensure a fair trial and the privacy of those involved.

Nonetheless, Siegler shared, “We always ask the judge if we can film it so we can talk about that part too. You have to have a judge on board. So we haven’t been lucky enough to do that yet, but we’re still working on it.”

And for the cases that don’t result in an arrest, Cordova said that Siegler and the other Cold Justice investigators continue to check in with local law enforcement. Cordova explained, “It doesn’t just end when the episode ends. The whole team is always trying to figure out what’s next and how it’s gonna pan out later on.”

Prosecuting Evil with Kelly Siegler premieres Saturday, November 18th at 8pm ET/PT. Cold Justice is now streaming on Oxygen and Peacock.
