Holly Bobo was a young, beautiful nursing student on her way to school one morning when something went horribly wrong. The 20-year-old vanished. Years later her bones were found in a remote spot off Interstate 40 in western Tennessee. What reportedly happened to her is depraved. 

This week Diamond State: Murder Board dives into the murder case of Holly Bobo. Private investigator Heather Cohen shares her experiences working on this case as a volunteer in this week's episode. Fair warning. The details are graphic.
