Tom Voigt was recently interviewed by CBS8 News in San Diego regarding the 1962 Ray Davis and 1964 Swindle murders, and their possible connection to the same individual responsible for the Zodiac Killer murders in Northern California in the late 1960s. Tom Voigt is correct when he says he doesn't "understand why agencies withhold information after all this time. The police departments aren't that forthcoming. They are not doing the victims any justice, as they can still get a prosecution. The guy could still be alive". The same could be levelled at the Riverside Police Department, sitting on information with respect to the murder of Cheri Jo Bates on October 30th 1966. Although this case, along with aforementioned murders are heading towards the 60-year mark, the suggestion that the Zodiac Killer may have been responsible and could have made mistakes in the infancy of his murderous career, is a reasonable assertion. The majority of serial killers will learn from their mistakes with time, often refining their approach to avoid capture. However, there is a possibility that towards the back end of their reign, they begin to feel impervious to capture and begin to take greater risks. This too could provide an opening.
Tom Voigt is again correct that the answers could possibly lie outside of the four canonical attacks, which have literally been examined to breaking point. Rather than solely pinning our hopes on the search for DNA within the Zodiac communications, it is imperative that we don't put all our eggs in one basket. Linking the Zodiac Killer through different cities and using geographic profiling to pinpoint locations within those cities, could provide a common name to investigate. Tom Voigt also stated "It's amazing to me that the murder of Ray Davis was not to linked the Zodiac until earlier this year. There was nobody in the Zodiac world, professional or amateur detectives - nobody had ever heard of the murder of Ray Davis (which) it's clear is probably a Zodiac murder. I think there are other cases like that in Southern California in the early 1960s, and I think it's crucial to focus on that area in that time period". While I agree again, there appears a contradiction when investigating the Zodiac case for potential leads. While the Ray Davis murder has rightly been hailed as a good avenue to pursue, there is another case that has been routinely ignored by virtually all amateur sleuths, despite the fact it has thirty pieces of ballistic evidence and an accompanying Zodiac letter. Not only does it have viable cartridge cases and bullets, it also has closer parallels to a known Zodiac murder than that of Ray Davis. Yet this crime lies virtually abandoned.
The two murders occurred on April 22nd 1986, and were featured in a Zodiac letter just two weeks later. I won't expand on this particular case any further, not only because it has been covered multiple times before on this site, but because no agency I have contacted is the slightest bit interested. Tom Voigt was amazed that nobody had linked the Ray Davis murder to the Zodiac until earlier this year, yet the Sacramento murders on April 22nd 1986 have been linked to the Zodiac Killer since 2013, but have essentially been ignored, gathering dust to this day. The constant search for answers down south is certainly an avenue worth investigating, yet the search for answers on the doorstep of the Bay Area under the Zodiac umbrella, seemingly appears an avenue worth ignoring. The contrast in approach to these two cases couldn't be more stark within the Zodiac community. It isn't just the police agencies we should be looking at. Cooperation is lacking at every level.
