This is the third in a series.

On Friday, May 30, 1969, two college girls left the Somers Point Diner for Pennsylvania. Their car was found on the Garden State Parkway a few miles away.

Three days later the bodies of the two girls, Susan Davis and Elizabeth Perry, were found in the woods near where the car was found abandoned. A massive police search found the girls’ pocketbooks with cash still inside. A diver’s watch was the only clue.

Several witnesses said they had seen the girls pick up a hitchhiker, but nothing led to an arrest.
