Horribly similar to the West Memphis 3 case, particularly in the sense of using suspect, inconsistent testimony from a juvenile that's not all that there.
There was a suspect to pin it on (in the end) with the WM3 mind you. With the Averys, it's either he did it, the cops killed her or it was Bobby Dassey and/or Scott Tadych. I don't think they made enough of a case of that, the second Kratz was able to play the indignant cop/prosecutor, he stitched up the case, with the a little help from the FBI. No US jury is going to return a verdict that the cops set someone up, can hardly get them prosecuted for shooting people stone dead.
