i'm thinking that they have not got enough dna evidence....jmho....taking too long if they had good samples it could be quick.....remember FBI was involved.....in the case of Jenise Wright Bremerton they had dna matched within a week then the arrest
You could be right. Which would be horrible if they can tell she was assaulted, but not enough DNA to pin it to the correct person.
But then again, in the case of Zachary Dunn (Ohio-6 year old female found alive), they arrested him for the kidnapping in July. And though she was found naked, and surely her sexual assault was obvious to the doctors who examined her, he was not charged with sexual assault for two months.
6 year old abducted July 26th, Zach arrested that night.

Indictment for rape September 26th (and this was the first news media confirmation of rape, up until then, LE and the media made it seem like they were still trying to determine whether she'd been assaulted.)

In the case of Zach Dunn, the victim was alive and alert, aware, so I think they were very confident in initially charging him in kidnapping, (witness saw him on the porch with her before they both disappeared) but LE waited until ZD's DNA came back to present all of it to the grand jury.
In this case, while it might just be they don't have enough DNA, or there just isn't any they can find, it could also be that they have JR off the streets and the other child out of that house, so the DNA comes back when the DNA comes back. JR isn't going anywhere.
Honestly, I don't understand why they just don't go for capital murder anyway--rape or no. I believe her age alone makes it a capital offense in Arizona, does it not?
