In the second part of our Zodiac Killer coverage, we explore 2 separate attacks. First we examine the September 1969 attack on Cecelia Shepard and Bryan Hartnell in which the killer wore an executioner's hood while he repeatedly stabbed the couple in broad daylight at Napa County's tranquil Lake Berryessa. Next we look at the October, 1969 murder of cab driver Paul Stine in which he shot Stine in San Francisco's most upscale neighborhood signaling a departure from the couple's normal MO of targeting younger couples. After the murder of Paul Stine, there was never a confirmed Zodiac attack again.

On 12/20/68, teenagers David Faraday and Betty Lou Jensen were murdered on Lake Herman Road just outside of Vallejo. Seven months later just after midnight on July 5, 1969, , Darlene Ferrin and Mike Mageau were attacked a few miles away at Blue Rock Springs Park. Darlene died but Mageau survived to provide police with some information. It was just the beginning of the Zodiac Killer mystery; a serial killer who would terrorize the SF Bay area for half a decade

On October 30, 1966, 18 year old college Freshman Cheri Jo Bates was brutally murdered on her college campus at Riverside City College in Riverside, CA. She was savagely stabbed and her throat slashed. Her murder shocked the quiet Southern CA city. Residents wondered who would kill the pretty and popular cheerleader. Police theorized that Cheri's killer disabled her VW Bug while Cheri was in the college library and when she came out to leave and found her car disabled, the killer came along acting as a good samaritan and offering help. After gaining Cheri's trust, he led her to a dimly lit alley between two abandoned homes on school property and initiated his attack. 30 days after Cheri Jo was killed, an anonymous typed letter was sent to police & the local press claiming responsibility for Cheri Jo's murder. Police initially believed that the confession letter contained details only the killer could know, but in reality, much of what was in the letter was published in AP news stories about the case. Additional letters would come in Cheri Jo's case 6 months after her murder. This time the hand scrawled letters were sent to not only to police and the press, but cruelly, also to Cheri Jo's father.
