They said he was released because of some problem with the trial; the victim had committeed suicide and therefore he couldn't face his accuser. There was a recent decision from SCOTUS that substantially restricted the use of hearsay evidence in such cases; I would guess it was related to that decision.
Why they didn't petition for a new trial is beyond me.
I learned something new. :)
It really pizzes me off!
