The cable network said Wednesday it has ordered eight episodes of the show. It is being executive-produced by Dick Wolf, Dan Cutforth, Jane Lipsitz and Tom Thayer.
"In small towns across America, cases involving violent crimes can often go cold because of a lack of funding, resources and state-of-the-art forensic technology," TNT said in a news release. "With the right resources, though, many of these cold cases can be re-opened and solved, bringing dangerous criminals to justice and providing closure for the families of their victims."
Set to debut this summer, the series stars Kelly Siegler, a Texas prosecutor for 21 years who has successfully tried 68 murder cases, and Yolanda McClary, a crime-scene investigator who worked more than 7,000 cases in her 26 years on the Las Vegas Police Department, the network said.
