The Pennsylvania Murder Mystery
"Somebody better help that girl"
In November 1969, student Betsy Aardsma had returned early to Penn State University during Thanksgiving to finish researching for an English paper. She went to the university library, where she entered the stacks to locate a book. Not long after an unknown man told the desk clerk something about a girl needing help. Betsy was found soon afterwards, collapsed on the floor, suffering from an apparent seizure. She died before the paramedics arrived and it was only after she was taken to hospital that doctors realised someone had stabbed her in the heart. Investigators were then looking for a brutal and callous killer who left very little clues as to their identity.
