I personally think he had a partner that wrote the letters and think that there were others involved, but I have no idea how many. I am 50/50 on Z being involved with some sort of political and/or religious group. It never hurts to look into these things. The more doors that are open the better.
I don't think Z would have been a SLA member either, but it is possible. I think there was a better chance he was in another organization.
Fair enough - and I agree that it doesn't hurt to look into things, within reason.
No proof that he acted alone in the killings? Well...no. But then again, there's no proof of a Team Z either. My main problems with the latter (in various forms) are these:
There is absolutely nothing remotely substantial which indicates a connection between the victims. If it was a team, or a group, or an organization - they seemingly targeted random individuals. That's very uncommon.
Even if they DID target random individuals, you'd expect some kind of agenda to be behind it. Something political or religious (satanists, cultists, radicals...something), but there is nothing substantial which indicates this either. Neither the murders (not even Berryessa, IMO) nor the letters point to any agenda beyond, well, trying to appear as infamous as possible.
Lastly, the old "three can keep a secret if two of them are dead" principle. Nobody has ever claimed (not even pure crackpots, to my knowledge) that they were part of a Team Z effort.
