They dropped the charges on her and JY though didn't they.
In fact Ms Riddle testifying today started of as a strange coincidence because this morning I began to search out articles about this case so I could understand the backstory better. I never knew about the kidnapping in Alabama until this morning. I found an article that said that Alabama has charged JG with felony kidnapping. I was even wondering who Ms. Riddle was and then oops there she is testifying in the case today.
But as I read the many articles out there on this case I became more convinced that JG only changed his story from 'Jr did it' to 'oh wait I did it' when he knew he was most likely going to prison for life on the Alabama charges anyway. He not only kidnapped the woman making her drive over 100 miles but he also forced her to pay for their hotel room and he did this by force using a firearm. So he is in deep do and he knew it. Before it comes to trial additional charges could be added against him such as an enhancement for using a firearm in the commission of a felony and armed robbery.
So that is why he has changed his tune (story) IMOO.
I actually think now it was JY who lured Trey down to the site where he was murdered. Trey would trust a young person more his age like JY and JY took full advantage of that. I also think now (unless something comes out to change my opinion) that JY was the sole murderer of Trey. I do however believe that his father knew it was going to happen and was pleased with his son for doing it.
IMO
