EDIT However, reading both of the AP News articles on this now, it does serve to sway me more toward his innocence. Crazy that the prosecutors withheld this at that time.. Par for the course unfortunately I guess.
Seems as though the SA office is trying to do the right thing now, and appears they will continue investigating, and hopefully if appropriate, may deem that the next best step is to drop his case fully and prosecute the other now-uncovered suspects.
