His mother, Augusta Wilhelmine Gein (who died on December 29th 1945), was a domineering woman with an intense hatred for females, but whose death from a stroke left Edward Gein devastated and alone in the farmhouse. Soon after his mother's death, Gein began to create a "woman suit" so that "he could become his mother and literally crawl into her skin". He would achieve this by exhuming the bodies of recently deceased middle-aged women from local graveyards and using their skin to fashion his grizzly creations.
A well read Zodiac Killer was seemingly inspired by the continuing fascination of the story of Edward Gein, that featured in many movies, beginning with Psycho (1960), produced and directed by Alfred Hitchcock, and starring Anthony Perkins and Janet Leigh, along with later productions such as The Texas Chainsaw Massacre (1974) and The Silence of the Lambs (1991). The Zodiac Killer mailed a cryptogram and letter in the middle of 1971 (likely early May) claiming the murders of Kathy Bilek (18), Debra Furlong (14) and Kathie Snoozy (15), who had all been recently attributed to Karl Francis Werner in the newspapers. The Zodiac Killer would make reference to all three girls in his 148 character and letter, asking investigators not to listen to "phonys" such as Werner, and warning them he would "skin three little kids and make a suit from the skin", and "send a patch of human skin if their is some left over". Having claimed the brutal stabbing of Snoozy and Furlong on August 3rd 1969 in San Jose through the "Aug" reference in his November 8th 1969 "Dripping Pen" card, he was now left with the necessity of claiming the stabbing of Kathy Bilek also. She became the focus of his later Monticello card, mailed on July 13th 1971, stating "Near Monticello Shought Victims 21 ...... In The Woods Dies April". Kathy Bilek was stabbed in the Villa Montalvo woods in Saratoga (near San Jose) on April 11th 1971.
I have always assumed that the Zodiac Killer was promising to kill three more kids in the future and make a suit from the skin, but based on the possible inspiration of the Edward Gein story, was the Zodiac Killer suggesting the macabre intention of visiting the three graveyards of Snoozy, Furlong and Bilek, and removing their skin to create a suit? Then mail "a patch of human skin if their is some left over".
This may seem far-fetched, until you discover that Kathie Snoozy was buried in the Oak Hill Memorial Park & Cemetery in San Jose, located in the neighborhood of Monticello, near Saratoga. Hence the wording "Near Monticello Shought Victims 21 ...... In The Woods Dies April" in the Zodiac Killer's message on July 13th 1971. The neighborhood of Monticello is near to the Villa Montalvo woods in Saratoga, where Kathy Bilek was brutally stabbed to death on April 11th 1971. There is no doubt that the Monticello card is referring to the murder of Kathy Bilek, through the gravesite of Kathie Snoozy - and so linking the Zodiac Killer to all three girls. But did the 148 character cipher and letter have a much more sinister connotation to its contents than first thought, inspired by the continuing story of Edward Theodore Gein?
