I have long discussed the probability that David Faraday tried to wrestle the gun from ZODIAC. After all, David had a lump on his cheek and his class ring was almost twisted off his finger, indicating a struggle. The ring in particular indicted grasping and clutching, as a wrestler would do. The young lightweight wrestler from Vallejo High was no match, however, for the beefy ZODIAC.


Journalist Victor Cantu, however, brought up the point that there would be ZODIAC DNA on Faraday’s shirt, certainly on his sleeves (he wore a blue long sleeved shirt). I don’t know if that shirt is still in an evidence locker. Nor do I know how much contamination it had. But it may be worthwhile pulling it and checking it to see if DNA that matches The ZODIAC stamps can be found.


From the stamps on ZODIAC’s nasty missives, DNA was finally extracted decades later.  But no one is entirely sure it is ZODIAC’s, though it seems probable. However, if David Faraday and ZODIAC locked in a wrestle, his DNA should be there.

Since there could be much contamination, the easy way for the DNA to be positive is for it to match the stamp DNA.

What if the stamp DNA is not ZODIAC’s? In this case, a process of elimination will have to be done. This would be costly. David went to a musical that night. But it is unlikely he would be touched in areas where ZODIAC would have touched him in a brief wrestle for the gun.

So what it comes down to is lifting DNA and trying to match to the stamps. If not, then process of elimination with the police/medics who handled it.  It also comes down to location of the DNA on the shirt and any pattern to it that would indicate more than casual contact at a musical. It is the pattern of the DNA on the shirt that would make a link likely. Tedious, yes. But it may finally give us ZODIAC in undeniable DNA form.

  1. The pre-cut bindings at Berryessa could potentially also contain touch DNA. He wore gloves at the scene but he mayn’t have worn them when the line was cut. Hollow core clothes line with its rough exterior surface full of nooks and crannies would be a great source for extracting DNA. If it is still around, that is.


  2. DNA from the inside of gloves he sweated in, left hair and skin flakes in would be even better than stamps that someone else may have licked or touched.
