That is interesting. I'd suspect he could possibly be found guilty of attempted murder, and have the sentence reduced or eliminated by arguing that his previous sentence unjustly assumed guilt for this as well, and factored it into the sentence he already served.

If I remember correctly, there were comments from both the prosecution and judge that would basically prove that point- and they allowed evidence related to those other crimes in the trial. If they could prove this misconduct, they may even be able to argue double jeopardy.
