In the aftermath of the Lake Herman Road double murder on December 20th 1968, law enforcement combed the turnout for ballistics evidence well into the next day. A supplemental investigation report listed the 2 bullets removed from Betty Lou Jensen's body at autopsy, the bullet retrieved from her panties and the bullet found on her "blood splattered path" on the turnout floor. It described this bullet as exiting from the center of her stomach and falling to the ground without penetrating the front of her dress. Only 4 of the 5 bullets were noted. There were 5 bullet holes in the rear of her dress and only one to the front of her dress. The bullet wound mentioned as passing through her stomach was described at autopsy as the one that entered "the tip of the right 12th rib, 3 and 1/2 inches from the midline", penetrated the liver and exited "below the xyphoid process and 1/2 an inch from the midline". This is entry wound 4 on the diagram, described in the supplemental investigation report as being found near her body in the turnout - backing up the contention that this was very probably the final shot fired by the Zodiac Killer that night, as Betty Lou Jensen was hunched forward, before collapsing backwards onto the ground. Both the bullet found in her panties and the bullet that fell to the ground had both lost such velocity through her body, that neither penetrated the front of her dress.
The exit wound (furthest red circle to the left in the diagram) is described at autopsy as "over the left interior chest laterally and left margin of the breast, in the 4th intercostal space and 5 and 1/2 inches from the sternum". This is the bullet wound that caused the hole in Betty Lou Jensen's dress and had an extreme right to left trajectory, fired by the Zodiac Killer as her right side was predominantly facing him at very close range. If this bullet had lost comparable velocity to the other two bullets that exited her body, it should have been found just a few feet to the right of the Rambler, close to the cluster of shell casings that peppered the turnout floor. Yet this bullet was seemingly never retrieved from the Lake Herman Road turnout, despite an extensive search by law enforcement. In fact, this bullet was never documented as submitted items in the Department of Justice report either (see below).

So what happened to this bullet? Despite traveling across her body at an extreme right to left trajectory, can we expect this bullet to have retained a markedly higher velocity than the other two "exited bullets", that it flew out of the much larger turnout of 1968? Or did the Zodiac Killer retrieve this bullet from the turnout floor using his "pencil flashlight", to later mail in a letter alongside the shirt piece of Paul Stine, thereby proving he was responsible for the murders of the "people in the north bay area" as well. The opening section of the October 13th 1969 letter referring to the San Francisco murder through the evidence of the shirt piece, with the bullet being the evidence for his following line of "I am the same man who did in the people in the north bay area". This (if it happened) would be two crime scenes where the Zodiac Killer took evidence away, with Lake Berryessa being the crime scene where he left evidence behind.
Bearing in mind we have two documents that have failed to itemize the same bullet that exited Betty Lou Jensen's dress, it is rather unusual that a 1995 BBC2 documentary called "Great Crimes and Trials" stated that "any doubts about the killer's identity were dispelled the next day when a letter from Zodiac arrived at the San Francisco Chronicle. With it was a bloodstained piece of the driver's shirt and a bullet from the same pistol that had killed Jensen and Faraday". We do come across errors in newspapers and documentaries, but considering we do have a "missing bullet" from the Jensen/Faraday murders, this outrageous claim doesn't seem so outrageous after all. It certainly isn't unusual for law enforcement to withhold evidence from the public to distinguish between any future hoaxers and the real murderer in any crime. But was this one instance?
