In the late 1970s, suburban Pittsburgh, Pennsylvania lived in the fear as an apparent strangling serial killer hunted young women - walking to school, leaving work. With so many other murders occurring in the area at the time, police originally didn’t know if any of these cases were connected. But soon, DNA would pin at least two of them together, and a consistent MO would help pool a collection of these horrific murders under the same umbrella. This is the story of the Pittsburgh Phantom.

In September of 1977, a promising 19-year-old college student in San Francisco disappeared after heading to study in her university’s library. Horrifically, she was found brutally murdered the next morning in a locked faculty reading room on the fourth floor, her belongings neatly piled nearby. With an attack on another local woman occurring in the same area that same summer, an intriguing and disturbing suspect came into play. This is the murder of Jenny Low Chang.

In September of 2009, a 24-year-old woman was released from a Los Angeles sheriff’s station in the middle of the night after being arrested for failing to pay her bill at a Malibu restaurant. In the hours preceding her arrest, she had been acting strangely and speaking in riddles. She had no car, phone, or money, yet she seemed determined to set off into the dark hills of Malibu Canyon, and was never seen alive again. This is the strange death of Mitrice Richardson.
