TNT says it has ordered a second, 10-episode season of its U.S. docu-drama series "Cold Justice" to air next year.

Produced by "Law & Order" creator Dick Wolf, the show follows ex-prosecutor Kelly Siegler and former crime-scene investigator Yolanda McClary as they set out to solve small-town murder cases that have lingered for years without answers or closure.

The first season of "Cold Justice" is to end Oct. 22.

"We're very proud to be renewing 'Cold Justice,' which has already delivered real-world results for several of the cases featured on the show," TNT's David Eilenberg said in a statement Monday.

"Viewers have come to see Kelly and Yolanda as a real-life counterpart to such [female] crime-drama duos as Cagney and Lacey, and even our own Rizzoli and Isles."
