Who Killed Betsy? Uncovering Penn State University's Most Notorious Unsolved Crime

On November 28th, 1969, Betsy Ruth Aardsma was murdered inside Penn State University's Pattee Library, by an unknown assailant. Thousands of students were interviewed, but no suspects were produced by the police investigation. 41 years later, the case remains unsolved. This book explores the turbulent environment of the late 1960s at Penn State, along with the details, the suspects, and the reasons behind why the killer was able to escape justice for so long, as well as revealing the main individual now suspected in the murder -- a Penn State University graduate student named Richard Charles Haefner who was uncovered by the author and another researcher during their time spent looking into the case.
