Jennifer Eileen Guyn, 23, was last seen on the evening of October 9, 1969, leaving First Christian Church in Mesa after choir practice. She was driving a dark blue 1968 Volkswagen and was headed to her Phoenix apartment for dinner with her roommate. When she failed to arrive and then missed piano lessons the next day, her roommate reported her missing.

The Volkswagen was found abandoned in a parking lot on the 3600 block of North 52nd Street in Phoenix and is believed to have been left there October 10. On October 13 an unknown man using a false name called a towing company claiming the car was his and broken down; the company held the vehicle and notified police only on October 28. The car was operable and contained Jennifer’s diary and address book. Her diary showed some neat entries and some messy, hard-to-read ones; investigators suggested she may have been distressed. She had ten dollars and her belongings remained in her apartment.

The unidentified caller who arranged the tow is considered a key person of interest. Did anyone in Phoenix at the time know the man who contacted the towing company or recall seeing Jennifer’s Volkswagen in that parking lot around October 10?
