February 6, 2026·51 min·1 clip
Ten years later on Thanksgiving, hunters found bones in a remote cemetery - two of the three girls identified by dental records.
As heard by us
A four-murder cold case moves from a 1976 disappearance to a Missouri killing, with grim facts met by uneasy panel humor.
James B. Grinder's link to four murders comes into focus through a cold-case trail that starts with the 1976 disappearance of Teresa Williams, Cynthia Mabry, and Crystal Parton in Russellville, Arkansas, then extends to Julianne Helton's 1984 murder in northern Missouri.
Why you'd press play
You get a grim cold-case arc: three Russellville girls vanish in 1976, and the answer finally comes after Julianne Helton's Missouri murder is solved in 1998.
