University of Utah track and field star Lauren McCluskey had everything going for her. Until she met Melvin Shawn Rowland at a club, and started dating him. Melvin told Lauren he was just 28, and a college student like her. But he was really 37, had a child – and had done ten years in prison for a sex crime. When Lauren broke up with Melvin, she started receiving bizarre and then concerning texts, and then the sextortion started. Lauren went to the campus police for help repeatedly, but her cries for help went unheard. On October 22nd, as she was on the phone with her parents, Melvin grabbed Lauren outside her dorm and shot her 7 times. The school had ignored all the warning signs – and Lauren McCluskey paid the ultimate price.

In 1966, Riverside City College student Cheri Jo Bates was viciously stabbed 42 times and nearly decapitated in an alley after leaving the school library. Police discovered that her car had been deliberately disabled, and concluded that her attacker had deliberately sabotaged it in order to get to her. The case was thoroughly investigated, but had started to cool when an anonymous confession letter arrived – claiming responsibility for the murder in great detail. Additional letters added to the mystery. And then, another killer dominated the headlines in California – a killer who also sent anonymous letters that bore marked similarities to the confession letter. Was Cheri Jo Bates the first victim of the serial killer who terrorized California in the late 1960s, who has never been identified – the Zodiac?

In 2009, pharmacology graduate student and soon-to-be bride Annie Le went to her research lab in the basement of a medical research facility at Yale University. She never left. She was finally found on her wedding day, stuffed into a tiny hole behind a wall panel in the laboratory building locker room. Investigators knew that her killer had to be someone with access to the facility – someone who, like Annie, was affiliated with Yale. And it was not long before they homed in on their suspect – a laboratory technician with no known relationship with Annie. What motivated Raymond Clark III to kill Annie Le?
