I dont think its a question of creativity. As a graphic artist and web designer, I'm pretty sure I have that trait in spades.
What people are asking us to do is throw away our common sense, intuition, and known facts in this case, to look at other suspects....because they cant or wont see WH's guilt.
I see no reason to handicap myself this way just to make them happy and will point out that so far every "finger" Ive seen, including that of his sister, points firmly at WH.
It's a strange situation right now because there is a mountain of circumstantial evidence that all points directly at WH (including every single thing he's said or done since the disappearance) and no one else, but of what is known publicly, it's all still circumstantial.
On the other hand, without a single piece of direct forensic evidence (in the public), what is out there now is not nearly enough to convict him (in connection with the death anyway, he's still on the hook for the stuff he was already arrested for), so that leaves the door open that maybe it wasn't him.
But when you actually open the door and look for someone else who looks like a viable suspect, it's nearly impossible to find anyone, so you're back to one guy with a mountain of circumstantial evidence against him and no one else with anything.
One thing that sticks out to me is that there IS forensic evidence in this case. It's only known to LE, though, and not publicly. LE has been acting as if WH has been the focus of their investigation from the start, and it's only intensified with arresting him for ancillary charges, questioning witnesses at the search sites about his vehicles, and bringing in speech analysts to look at his interviews. If the people who DO have the forensic evidence are focusing on him alone, that could be a clue that the forensic evidence also points to him, but that's only a supposition.
Frankly, my opinion is that there's no chance he doesn't know what actually happened. In addition, I find it highly likely that he is directly involved in the disposal and coverup. What I'm not certain of is what happened and whether there is even a murder. We need the tox report and ME report to determine COD and MOD. I have not been able to rule out scenarios where AJ and mom get into a fight and AJ calls WH and goes over to party with him in his hotel room. Partying out of anger often leads to excess, and I still cannot rule out accidental OD or even some natural death (heart failure or something) while partying with WH. With his past & mindset as a convicted felon and his involvement with cocaine (even possible distribution), he may think he can't just call 911 and have an ambulance get her from his cocaine and firearms laden hotel room that may be a local drug distribution point, especially if she is not breathing and possibly in his mind already dead. I know that sounds callous, but this is a criminal mindset we're dealing with.
I don't think that this is a likely scenario, but it is plausible enough that I have enough uncertainty about what happened to say for sure it is a murder. I think it's more likely he did actually snap and kill her, too, (IMO only of course) but that's what we're waiting for the forensic evidence to back up or refute. Again, I do not see even close to enough direct evidence to convict him on that yet.
As for anyone else's involvement, I haven't seen enough to say that I think there is definitely anyone else involved (let alone who it is). It wouldn't shock me if someone else was involved in the coverup, although, again, I don't really know who that might be. At this point, while nothing can be ruled out 100% I guess, I do NOT believe that JH is involved in this in any way, other than poor judgment in marrying a violent felon while raising three young daughters, but that's not a crime, either, just a mistake in judgment for which she's already paid far too heavy a price.
I also believe this whole adoption/name change discussion is a red herring. If there is a sexual motive (another thing that I haven't seen nearly enough evidence to say I believe that), WH wouldn't need to adopt AJ to have access to her. It seems like a lot of the motivation is to defend Zach as her "real" dad and discount the possibility that AJ actually wanted to take WH's last name. This is a dangerous and slippery slope for us to take. We really don't know anything about that, and as I've said before, the divorce/custody situation between Zach and JH has been ongoing for a long time and is clearly very contentious, and we only have one side's biased perspective. I know people here love Zach, and he is clearly a genuine person who wears his emotions on his sleeve and has been a valuable asset to this community, but we really shouldn't be projecting our feelings about him onto this custody/adoption situation. I don't find it unreasonable at all that AJ might have actually decided herself that she wanted to change her name. And I don't think that is relevant at all to the case either way.
