'Cold Justice' winter finale video: Kelly and Yolanda investigate a double homicide

As "Cold Justice" comes to its winter finale, investigators Kelly Siegler and Yolanda McClary head to Iowa to investigate a double homicide from three decades earlier. Can they find out who killed a young couple after so many years?

In 1983, 20-year-old Steven Fisher and his girlfriend, 17-year-old Melissa Gregory, were killed by brutal blows to the head. Family troubles and rumors of drug trafficking both figured into the investigation, but the case was never solved.

"Cold Justice" attempts to do just that when it airs Friday, March 28 at 8 p.m. ET/PT on TNT.
