I don't think he was a completely "natural" speller - no. I think the Badlands letter demonstrates that - but it also demonstrates that he could certainly spell very well indeed when disposed to do so, or that he reached for a dictionary when he reached his limits. "I would like to express my consternation" huh?
Badlands is what it is, I guess. I'm not sure it was written by anyone but a "citizen" myself. But in general I'm open to the idea that he could have reached for a dictionary. I don't think he was a pathologically bad speller - just a bad one. Plus a really careless one. Plus something else on top of that.
You think maybe he didn't compose written texts in standard English frequently? I can't imagine anyone would bother to learn Gregg unless they did, frankly.
If he was a reporter then he may have used a typewriter more often than a pen, yes, but either way I think he did write - often.
Fair point. I suppose people who used Gregg would also be - as per their work, which is why they learned shorthand in the first place - required to write plenty. Not their own things, though, as much as mechanical reproduction work. But, yes - it's a bit hard to imagine an incredibly poor speller working as a secretary, say.
Yes, he was decidedly non-deferential in his attitude - at least in the letters.
Glad we agree on that, at least.
Yes he seems to have known shorthand well, very possibly to a professional standard, (whatever that might mean.)
Well, it means that he probably used shorthand in a professional capacity. As a secretary, for instance. I can't imagine many people would have bothered to learn shorthand unless is was for work. And it wold seem too much of a stretch to propose that our letter writer was someone who learned shorthand just for the purpose of writing the Z letters - no?
What's wrong with the picture? Well, there's an elephant in it.
There is? The hoax business you mean? Or something else?
I'm still a fan of the "letters written by a hoaxer" view - which is undoubtedly strengthened by the idea that the letters were put together by a journalist or a reporter, yes indeed-y. Skilled writer + access to information from a reporter's perspective = Riverside Confession letter and indeed allllll the rest.
Not that people in those careers can't become multiple murderers, of course, but hey, this background certainly helps if you did NOT commit any murders....
Isn't a pity about the shirt and the car door eh?

Yes - I gathered as much. And yes - no doubt, a journalist or reporter might very well have had knowledge of shorthand. So I can see why you'd be interested in that angle - certainly. I'm interested in it for a slightly different reason, I suppose - but that's alright. Interesting is interesting.
Can I ask you a question, smithy? And this is meant in all openness and honesty - I respect you and I like your style as a poster even though I don't necessarily share your convictions (or suspicions, more like it, perhaps?): Without getting into precisely who did what and when - WHY did he or they construct this thing? What is the motive for the hoax? I'm not saying you absolutely, positively HAVE to come up with a motive in order to support the theory - but I do think it would help a great deal.
All the best,
