A woman's body was found on a truck stop parking lot in Springfield, Missouri in 1997 - far from her home near Memphis. Gloria Jean Barnes' body was discovered the day before her 36th birthday. No family gathering, no cake, no celebration. Gloria got an autopsy for her birthday. As police work on leads, all they find are dead ends. For the first time in over two decades, Gloria's sister and brother are speaking out about what they believe happened the night Gloria was taken from Joiner, Arkansas. A family's secret, a mother's crusade to catch a killer, and details in this case that have never been revealed. It's a cold case brought back to life by "The Toll: Hearts For Gloria."
