Episode 9 - After 50 years, the cold case unit is still adding details to the butcher paper roll that Detective Mike Davidson tacked on the wall of the Clark County Sheriff's Office back in 1976. A timeline of crimes, Warren Forrest has both been convicted of and suspected of. Including the disappearance of Diane Gilchrist and the murder of Gloria Knudson. Both young women matched his type and modus operandi. Could forensic sweepings collected back in the 1970s from Warren Forrest's van connect him to more cases? And possibly another murder charge? Or push him into a confession. After more than five decades, the eyewitness who claimed to have seen a woman tied to a tree in Dole Valley around the time Jamie Grissim went missing has been found. Could he help a K9 team narrow down the search for Jamie Grissim if her remains are in Dole Valley?
