On November 28, 1969, Betsy Aardsma was a masters student at Penn State and was last seen heading to an area of the Pattee library known as ‘The Stacks.’ No one in the library at the time heard or saw anything out of the ordinary other than a couple talking quietly and the fall of some books from between rows 50 and 51. What they didn’t know is that Betsy had been stabbed with one fatal blow to the chest while looking for materials for a paper she was writing. No one knew what had really happened until she arrived at the hospital, her dress seemingly absorbing all the blood into its red fabric. Her case remains unsolved to this day but there are more than one infamous suspects on the list of potential killers.
