Respectfully, I do not agree there is not a link of evidence, we just may not be privy to it, or it may only be known to Darlie. I'll grant it may or may not be circumstantial, but if it can be corroberated, that's about all it would take. And not to forget she has only been convicted for one of the boys, I personally believe that has something to do with this. There is no incentive for her to serve up Darrin as she would be putting the nails in her own coffin as well, and why would she until she has exhausted all of her appeal avenues?
I'm not suggesting they would swap one for the other, on that we agree.
But she would have to alive long enough to testify as a witness, no?
