Drew Peterson is a worthless POS who very likely was involved in the deaths of his two wives and I hope he rots in the lowest pits of whatever hell there happens to be.
On the other hand his conviction for those murders were based on 'Drew's Law', passed by the IL legislature, allowing 3rd party hearsay and innuendo.
I really, really don't like that precedent no matter how limited they claim it is because we've all seen what happens to 'limited' laws. They tend to get more and more expanded as it becomes convenient. Eventually no actual facts would be required and spectral evidence will once again be acceptable.
