The Monticello Card mimicked the Pines Card in the directional nature of the communication. The Monticello Card contained the phrases "in the woods" and "near Monticello", whereas the Pines Card stated "pass Lake Tahoe areas" and "Sierra Club". Both communications provided us with a specific location and directions, and it is my belief that both contained a punch-hole on the right-hand side of the card The combination of a punch-hole and directions should indicate that both these postcards were designed as an overlay, pinpointing a specific location. The Monticello Card read "Near Monticello Shought Victims 21 ...... In The Woods Dies April". The card was describing the murder of Kathy Bilek, who was brutally stabbed in the Villa Montalvo woods on April 11th 1971 in Saratoga. The location he pinpointed as Monticello, was a few miles east of the crime scene - but more important - was the reason he chose the neighborhood of Monticello in the first place. Immediately alongside the neighborhood of Monticello sat the Oak Hill Memorial Park & Cemetery, where Kathy Snoozy was buried. The Zodiac Killer had previously claimed the murders of Kathy Snoozy and Deborah Furlong (San Jose) in his November 8th 1969 'Dripping Pen' card by the addition of "Aug" in his running total. The Oak Hill Memorial Park & Cemetery would have sat under the punch-hole on the Monticello Card. This punch-hole would not only be over a memorial park, but over a burial site. The only reason the Zodiac Killer identified this location in Monticello, was to reveal the name of Kathy, the namesake of Kathy Bilek - and the final clue to the identity of the murder victim portrayed in the Monticello Card. The Pines Card followed exactly the same pattern, with the punch-hole again falling over a memorial park and the name of an alleged murder victim - that of Donna Lass. When the Pines postcard is positioned over the Sierra Club of Clair Tappaan Lodge, the punch-hole falls exactly over the Donner Memorial State Park. The Zodiac Killer gave us a memorial to Kathy and Donna in both instances.
There is only one route that fits the criteria of "pass Lake Tahoe areas" that runs directly from the south side of Lake Tahoe where Donna Lass was abducted from (Sahara Tahoe Hotel & Casino), to the area of the Donner State Memorial Park. From the Sahara Tahoe Hotel & Casino, a direct route from the crime scene to remote wilderness, could be achieved by taking US Route 50 and California State Route 89. It is approximately 30 miles from the casino along the south and west side of the lake, to the area I have identified. Furthermore, the area is alongside the Pole Creek Trailhead - a hiking trail the Zodiac Killer may have been familiar with. This location sits directly over the crosshairs of Zodiac on the Pines Card. I have drawn a green line from the location of the punch-hole (Donner Memorial State Park) to the crosshairs on the Pines Card. This green line straddles California State Route 89, with the crosshairs falling a few hunded metres to the west of Route 89, by the Pole Creek Trailhead, along Pole Creek Road.
