Just jumping in here- I feel like even if they can't get him on the murder charge (which they may have sufficient evidence and we may not know- hell, last time I thought LE wasn't doing enough- they had him arrested and charged before I could even read the next news update!)
Anyway, even if they can't sustain the murder 1 charge, LE has already said they can place him and his truck at Whiskey Bay and they have him on surveillance tapes following her- whether it be GPS or cell phone pings or tire marks or a combination, IMO they have him on the kidnapping charge. And considering NO-ONE has came to his defense, not friends or family, I really don't think he's going to walk tomorrow.
I also have the feeling that whatever was on the last tape LE obtained from the newspaper is particularly damning to his case. The arrest and charges came too fast for them to not know, without a doubt, he IS responsible- IMO, MOO, FWIW
And I just want to add, Mickey's sister is amazing. That last radio interview she did just broke my heart. Her compassion and poise simply amaze me. Regardless of what happens in this case, I hope, with time of course, that she can turn this tragic situation into a positive, and remain a voice, not only for Mickey, but all of the missing young people out there. So many heartbroken people faced with tragedy turn into heros- and I really think she has the charisma and passion to make a difference in this world. Its inspiring.
