I understand why you might be impatient for conspiracy, murder or other big charges, but at this point, I don’t think the state is in any rush.
First, because the govt has unlimited time. Since Lori and Chad won’t get sprung from jail, the state can focus on making the best possible case, which takes time.
It’s also in the state’s interest to let them stew in jail and constantly wonder what’s next. Not only will that bleed all of their $$ away, perhaps leading to changes in counsel, but it probably makes it more likely that one will turn on the other.
So I wouldn’t be surprised if taking a while is a specific strategy.
The state also has an enormous amount of evidence to plow through, just from what we know. And there may be much more we don’t know about.
Finally, the sheer incompetence of the AZ authorities likely plays a role in this taking long. They were months behind, bungled the CV murder, and even screwed up the evidence.
So if the CV murder plays a role in the overall prosecution plan, it’s taking an enormous amount of time to repair the incompetence in AZ.
In short, the wait isn’t a big deal, and it’s probably a sign that things are getting worse for the defendants.
