On Nov. 28, 1969, Betsy Aardsma, a 22-year-old graduate student in English at Penn State, was stabbed to death in the stacks of Pattee Library at the university's main campus in State College. For more than forty years, her murder went unsolved, though detectives with the Pennsylvania State Police and local citizens worked tirelessly to find her killer. The mystery was eventually solved—after the death of the murderer. This book will reveal the story behind what has been a scary mystery for generations of Penn State students and explain why the Pennsylvania State Police failed to bring her killer to justice. More than a simple true crime story, the book weaves together the events, culture, and attitudes of the late 1960s, memorializing Betsy Aardsma and her time and place in history.
