Armond Pelissetti is on tape, stating he saw the blooded taxicab prints on the dividing panel between the driver side door and rear door as he ushered the kids back across the street. This means (assuming Pelissetti is telling the truth) that those blooded fingerprints weren't deposited by any ambulance crew, reporters or errant wandering bystander, as people with suspects would like you to believe. Anybody who has a suspect with fingerprints on file, have set the default position to discrediting this partial fingerprint on the dividing panel, just in case it is able to eliminate their suspect from being the donor. Discredit this blooded fingerprint, by pouring doubt on its origin, and your suspect is kept in the frame.
Whether enough detail exists on this partial fingerprint to rule out people comprehensively, I don't know. But just in case, discredit it first and you have no worries. Did you notice the two Napa bookstore videos got removed from Youtube just prior to September 27th 2018?
