TNT has greenlit 12 more episodes of real-life investigative series “Cold Justice,” currently in its third season. The cabler also announced Wednesday the order of two “Justice Served” specials, hosted by John Walsh.

“Cold Justice” revolves around former prosecutor Kelly Siegler and former crime-scene investigator Yolanda McClary (both pictured with Walsh), as they work with local law enforcement to help close unsolved cases. The new episodes will feature the team investigating a surrogate mother’s disappearance, a newlywed’s disappearance, a well-respected doctor’s killing and a same-sex affair that may have led to murder.

John Walsh’s “Justice Served” will return with two “Cold Justice: Justice Served” specials, which will bring on Siegler and McClary to give an update on the recent cases featured on their show. The first special is set to premiere in May.

This summer, TNT will premiere “Cold Justice: Sex Crimes,” a spinoff centered around rape, sexual assault and abuse cases. A first look at the upcoming series will bow during the “Justice Served” special in May.

“Cold Justice’s” winter finale airs March 6, and the series is slated to return with new episodes April 10.
