Here is a list of connections that have been found so far to date. I’m going off memory, so if I’ve forgotten anything you’ve discovered, please contact me so we can get it in this list.
- The suspects tire tracks and description of car (from possible witnesses) at Lake Berryessa crime scene match the car my POI drove in 1969. The photo below (and above) was taken in 1969 at “the Ranch” (somewhere in Patterson, CA). You can see in this photo that the tires are mismatched in the front and look to be quite worn. The measurements taken by investigators indicated a tire track width that matches the tire track width found for this particular Sunbeam car.
- A document written by Mr. Colliver found by a user on a Zodiac Killer website shows a connection to the case by referring to women (whores) in Tracy, Vallejo and Benicia. It is a list of women’s names and suggestion of some other women that he had had sex with throughout his life.
- Film boxes were found in the garage of his home after he had already passed. They stood out as possibly being a clue due to the symbol drawn on them.
- The document below seems to be a confession of guilt. The wording “I have killed” and “I have a headache” remind us of the call made by the Zodiac Killer to the Jim Dunbar radio show where he claims to have “killed a kid” and he gets “headaches” because of it.
Here is a link to the timeline.
Taking the timeline above, Mr. Colliver was in the vicinity of crimes committed or possibly committed by the Zodiac Killer in each instance. No other suspect that has been brought forward in the case can be confirmed to their whereabouts during each crime that was committed except for Mr. Colliver.
Please click on the links for more information from the list below.
The names on this list above are unsolved murders that might be the work of the Zodiac Killer. They are all cases that are still open in the cities where Mr. Colliver was known to have been living or working in during the times of these murders.
The confirmed unsolved Zodiac Killer cases in the San Francisco Bay Area listed below also fit into the whereabouts of Mr. Colliver at the time they were committed.
There is also this connection:
This is the map the Zodiac Killer mailed June 26, 1970. The black circles with arrows point to dots that were discovered by a user on http://www.zodiackillersite.com. The two circles near Livermore represent the two dots that were found to be connected to Mr. Colliver.
Here is a closer version of the map. You can see the two dots, one over Pleasanton and the other is on Union City. Mr. Collivers home was where the Pleasanton dot is and his brother Ray lived where the Union City dot is.
The more I look into Mr. Colliver, the more connections I find.
The composite sketch has been the subject of debate from the very beginning of this case. Skeptics argue the fact that the sketch shouldn’t be taken too seriously since the witness descriptions vary in all of the cases.
Mr. Collivers weight fluctuated quite a bit in his younger days. His drivers license description varied from 150 pounds to 180 pounds and his height went from 5’6″ to 5’8″. He mentions in his documents where he had been consumed with something for 30 years and that now that it’s over he can focus on his next project. He then began to take on a strict exercise regime and built elaborate machines out of wood in his dining room and his garage. I believe his obsession with exercise was his way of working to change his appearance so as to relieve his guilty conscience.
Another criticized source of evidence is his handwriting. This is a comparison I did in 2018.
Mr. Colliver was an artist. He not only sculpted with clay, he also worked with wood and most notably, he drew portraits and people very well. After bringing his works to the attention of the Zodiac Killer community online, connections were found in some of his drawings.
What about these drawings?

Mr. Colliver had a very distinct voice. Below you will find links to audio recordings I’ve processed from cassette tapes he used to record his phone calls with various people. In some of these recordings, he talks about being on the FBI’s most wanted list, he casually jokes about killing masses of people and getting away with it, he discusses the unsolved murder case of Jon Benet-Ramsey and his favorite subject about how women are inferior and stupid, slow and worthless.
