Where is Sandra Yeoman?

In this episode, Sandra Yeoman's sisters, Iris  and Roxanne, join Chief Communications Officer Amanda Granit and Special Investigator Dan Bendig to discuss the disappearance of their sister when she was just 13 years old.  Not only do they want answers as to what happened to her, but they are pleading for anyone who may have a photo of their sister to come forward so they can better remember her almost five decades later.
