Dave Slaight and Bryan Hartnell The double stabbing at Lake Berryessa on September 27th 1969 has been constantly questioned as a Zodiac crime, often backed up by the argument that the Zodiac Killer never bragged to newspapers in the following weeks. On the face of it he didn't really have to, as Bryan Hartnell was able to recall virtually every chilling detail in the aftermath of the attack. To claim that the lack of correspondence by the Zodiac Killer after this crime is evidence of a copycat killer, is a false dichotomy. They are not the only two options. There are many features of this crime that suggest a Zodiac connection, but there is actually no evidence whatsoever to the contrary.
The first claim is that the modus operandi (MO) of the crime was totally different from the other three attacks. This is clearly not true. It was an attack on a young couple, seemingly random, just like the first two crimes preceding it, despite the sample size being relatively small and statistically weak. Had the killer not mailed pieces of Paul Stine's shirt with three subsequent letters or written to the newspapers, neither the police or anybody else would have likely connected this to the Zodiac Killer. The modus operandi would have been called into question. So claiming the Lake Berryessa crime as not that of the Zodiac Killer because it didn't marry up perfectly with the first two crimes, is again, not evidence of anything. Absence of perfect continuity is not evidence to the absence of Zodiac.
The message on the car door detailing his crimes to date shows distinct Zodiac traits in the handwriting, but expecting it to match up perfectly with his mailed correspondence is not a reasonable premise. He had just stabbed a couple sixteen times, his adrenaline was likely raised, he had then traversed back up the hill and proceeded to write on the car door of Bryan Hartnell's car, on a different surface, in larger handwriting, in a totally different position he would adopt if he were writing calmly on a desktop. The comparison between the two must take this into account, so the fact it looks somewhat similar to his mailed correspondence is actually quite an achievement. Had this been written by a copycat it would actually have been a lot harder, who not only had all of the above to contend with, but had to replicate the handwriting from an awkward stance or seated position, side on to the vehicle.

Nancy Slover The tone and phraseology of the killer in both phone calls to the police is virtually identical. After the Blue Rock Springs Park attack he stated "I wish to report a double murder. If you will go one mile east on Columbus Parkway to a public park, you will find the kids in a brown car. They have been shot by a 9 mm Luger. I also killed those kids last year.... Good-bye". After Lake Berryessa he stated "I want to report a murder, no, a double murder. They are two miles north of Park Headquarters. They were in a white Volkswagen Karmann Ghia" and after a brief pause uttered the words "I'm the one that did it".
It is possible a copycat read the transcript of the Zodiac Killer's first call to police in the newspapers, and reproduced its phraseology during the Napa payphone call. But why is it easier to believe that, rather than believing it was the Zodiac Killer. What evidence exists to promote a copycat making the call above the Zodiac Killer. There is none. The same can be said of the handwriting on Bryan Hartnell's Karmann Ghia.
In terms of the content of the handwriting, it is often said it was not the Zodiac Killer because his November 8th 1969 'Dripping Pen' card made reference to a murder or possible double murder in August, which the killer at Lake Berryessa did not refer to on the car door. But the reverse could be argued, that the reference to September in the 'Dripping Pen' card is equal proof that he was claiming the Lake Berryessa crime as his, particularly in light of no other valid murders in September where a killer wore a crossed circle costume and made a phone call with all the hallmarks of Blue Rock Springs Park. This again is a false argument. Even if the Zodiac Killer had murdered in August, the police were apparently unaware of this fact prior to the Lake Berryessa attack, so he simply wrote the dates of the crimes he knew the police would recognize.
At the top of the Karmann Ghia door the Zodiac wrote 'Vallejo,' so any murder outside of this area would have been unnecessary to include in the message. This indicated that the Zodiac believed that both the Lake Herman Road murders and the attack at Blue Rock Springs Park were both committed in the jurisdiction of Vallejo. This is understandable, because the jurisdictional line that separates Benicia and Vallejo is a short distance from the Lake Herman Road turnout.
The Zodiac, remember, never mentioned Benicia in any of his correspondence, but mentioned Vallejo several times. Curious then, that a copycat would make the same mistake and lump the 12-20-68 on the car door under the banner of Vallejo also. If this alleged copycat had read the newspaper transcripts of the Blue Rock Springs Park phone call, he certainly didn't take the time to read the multiple references in the newspapers to Benicia, when referring to the first crime on the car door. It could be argued that he studied the Zodiac letters intently and knew the tendencies of the Zodiac Killer, or we could opt for the more likely reasoning, that he was the Zodiac Killer.
Much debate has occurred on whether the man spotted by the three girls at Lake Berryessa was the assailant of Bryan Hartnell and Cecelia Shepard, with comparisons made of this man to the Presidio Heights sketch. Many have stated the two artist impressions are dissimilar in appearance, yet with a quick hair change and slight alteration to the eyebrows, the difference is much less significant between the two. Eyewitness recollections are also proven to be notoriously unreliable. These hair changes have been made to the Lake Berryessa sketch below, without altering any of the facial features.

The executioner's costume at Lake Berryessa is often used to discredit this as a Zodiac crime. It is claimed it wasn't his modus operandi. In this instance what MO? We only have two confirmed attacks by the Zodiac Killer as of September 27th 1969, one of which we have no idea what he was wearing, and both committed in virtual darkness. So, in terms of clothing we would actually be deducing that Lake Berryessa wasn't the Zodiac Killer, because he didn't wear the costume at Blue Rock Springs Park. Not a really convincing argument. When the scientific community needs to draw any conclusions from trials, or politicians from polls, the larger the sample the better. Drawing conclusions from a pool of one or two crimes is utterly meaningless, and falls into the category of subjective opinion.
In an ABC Primetime documentary the narration was as follows "However if Doctor Cydne Holt can find enough genetic material from Zodiac's stamps and letters, she can compare it to a wafer thin slice of brain tissue from Arthur Leigh Allen's autopsy." Dr Cydne Holt "This brain tissue from Arthur Leigh Allen is the reference sample that I would use for the comparison." Narrator "Dr Holt has already detected the possible presence of Zodiac's DNA in the seal of the envelope that contained the greeting card (Dripping Pen Card and 340 cipher), and just in case that test fails to provide a full DNA profile, she also prepares to look for DNA beneath the stamps on two of these three letters (July 31st letters)." Dr Cydne Holt "Depending on whether those DNA's match each other, might allow me to include or exclude Arthur Leigh Allen as potentially contributing the DNA on the Zodiac letters."
She was able to exclude Arthur Leigh Allen as the contributor, indicating a positive match was found between the letters. So if we maintain that the 'Dripping Pen' card and August 31st letters were mailed by Zodiac, and he claimed September as his crime, it lends credence to the Lake Berryessa crime being committed by Zodiac.
The Zodiac Killer probably believed that by writing on the car door and making the telephone call, it would be enough for people to conclude he was the killer. However, this has not proved to be the case. He probably believed that mailing a section of Paul Stine's blooded shirt would be proof enough. This has also failed in certain quarters. The details only known to him and the police at Lake Herman Road and Blue Rock Springs Park he thought would be enough, but it wasn't. The reality, is that for some people there is nothing he could have done to prove he was the killer.
If it's claimed that this crime had a totally different modus operandi to the first two crimes and was therefore not the Zodiac Killer, then the copycat was obviously not doing a particularly good job. A copycat attempts to replicate the crimes of a known killer. Therefore, we could conclude that by failing to stick to the known MO at Lake Herman Road and Blue Rock Springs, the Lake Berryessa perpetrator was more than likely the Zodiac Killer after all. But the fact remains, that not one piece of tangible evidence points to a copycat killer, only the idea that such a person exists.
