In “The Garden State Parkway Murders,” true crime writer and attorney Christian Barth dives into the harrowing story of the unsolved murders of Elizabeth Perry and Susan Davis. College friends, the two women were brutally knifed to death and their bodies left off the parkway in the early hours of May 30, 1969.

Among the numerous suspects Barth identifies are infamous serial killers Ted Bundy and Gerald Eugene Stano, who were living within an hour’s drive from the murder scene at the time they occurred. The killers also resided next to one another on Florida’s Death Row, and indirectly confessed to the double homicide.

A culmination of more than nine years of research, Barth’s book is compiled from multiple sources, including interviews with retired New Jersey State Police detectives, law enforcement officials from other jurisdictions, federal agents, possible witnesses, victim family members, as well as information gathered from FBI case files, letters, journals, libraries, newspaper articles, and university archives.

In scintillating detail, Barth presents the case, including previously undisclosed information surrounding these brutal murders, as well as an examination of recent technological advancements in crime scene analysis and FBI serial killer profiling that could help identify the killer. When all is said and done, the reader is asked to consider: Why hasn’t this cold case been solved? THE GARDEN STATE PARKWAY MURDERS: A Cold Case Mystery-Christian Barth
