Gotta disagree strongly. No dots have been connected. There's been NOTHING that puts ZA in that garage or taking HB away (and in fact, the opposite), nor is there any evidence she was in his company at any later point. No evidence that says he killed her. Lots of items that make you go "That COULD be related" but no links proved yet, not one.
So far, it's just a bunch of dots being offered. They gave evidence that someone took her. They say supposedly he drove around, did erratic and/or illegal stuff, he was a jerk to his GF and tried to intimidate her with references to HB being dead or missing. When the police came to his house, his appearance was subpar and he later did some things that can seem suspicious. But all could just as easily be innocuous, or related to other illegalities. They found some stuff in the woods, but so far we don't even know if they were his. And more importantly, there's NOTHING so far to tie him to any kidnapping or murder. Just because he's a druggie or an azz or a weirdo doesn't mean he's a killer - you gotta PROVE he did the crime. Dots connected? Not even a little bit. Yet.
BUT let me be clear. The lack of connections at this point, in a trial that will take weeks, doesn't matter at all. They have to start somewhere, and the 1st step is to give some dots. And it doesn't matter when in the process it happens, it only matters that they can (and do) connect him to this crime at some point. I'm waiting. I'm hopeful and optimistic. If he did this, he needs to pay. But only IF he did it.
