My opinions only, no facts here:
Another thing the Defense will have a strong argument on- the witness description of the kidnapper does not match either of the currently-jailed suspects. I have seen this explained away (the main suspect has lost weight recently, witness descriptions are unreliable, etc.), but this is a BIG deal for the Defense. With Holly for comparative scale, her brother very likely made a fairly accurate estimate of her kidnapper's height and weight. His and the FBI's longstanding description of 5 8 to 6 0 tall, weighing 200 pounds cannot be trivialized in a court of law. Since 6 feet is the maximum allowable height, the kidnapper is very likely shorter than 6 feet tall. The kidnapping suspect sounds like a short to medium-height stocky individual. Neither of the two currently jailed suspects fits this description. If I were a juror, this detail alone would create significant doubt in my mind. When you think about the minimum height estimate of the kidnapper (5' 8"), that is only 5 inches taller than Holly Bobo! And there is something else- men in the woods may be wearing boots with 1 to 2" of heel, insole, and socks. So, if anything, the kidnapper could even be a tad shorter than described.
Somehow, I think that if either of the currently jailed suspects (one at 6' 3" and 170 pounds and the other at 6' 7" and 250 pounds) were the kidnapper that Holly's brother saw, his description would have been decidedly different.
Look, the authorities could have arrested a 5' 6" 300 pound man and a 7 foot tall 150 pound man, and the assumption of guilt would still be there. And that is the problem, the assumption of guilt.
I would certainly expect the defense to hammer this. I also don't think it's that big of a deal. Descriptions like that are rarely if ever going to be spot on. I never understood everyone's questioning CB's involvement because of it either. Bottom line is he was guessing. Might have been his best guess, but he was guessing. Ask me my neighbor's height who I was just standing outside talking to for an hour and I really don't know. It seems like I was taller than him at 6' 0" but I also wouldn't be shocked if I went back over there and found out he was a couple inches taller than me.
