ABC 20/20: Stanford Murders

With one verdict just in, emotional interviews with the family of the convicted murderer. The all-new 20/20 true crime special breaks September 17, Friday night, at 9|8c on ABC – and stream on Hulu anytime.

In 1973, shockwaves ripped across Stanford University when three promising young women – Arlis Perry, Leslie Perlov, and Janet Ann Taylor – were murdered on campus within just 19 months of each other. For nearly five decades, the mystery of who committed “The Stanford Murders” remained unsolved until DNA matching technology finally linked a former Stanford security guard, to Perry’s murder. When investigators revisited the other two unsolved cases, new forensic testing revealed a DNA match to John Arthur Getreu, another former Stanford employee. On the heels of Getreu’s conviction yesterday for murdering Taylor, a new “20/20” features exclusive interviews with Getreu’s former step-daughter, Cathi Stone, who reveals Getreu sexually abused her from age 5 to 14; Evan Williams, the brother of 15-year-old Margaret Williams who Getreu killed in Germany in 1963; Susan, Getreu’s ex-wife who was married to him at the time of the murders; and Aaron Getreu, Getreu’s son from his second marriage who expresses shock and disbelief at his father’s arrest and sordid past. “20/20” features exclusive reporting and footage from the upcoming documentary series on the crimes, by Emmy award-winning investigative journalist Grace Kahng, as well as interviews with Sheriff Laurie Smith and cold case investigators Sgt. Rick Alanis, Sgt. Noe Cortez, David Tresmontan and Rick Jackson from Santa Clara and San Mateo counties working to solve the murders.
