I predict an 11th hour plea bargain. Failing that, a guilty verdict, though likely on a lesser included charge if that’s an option. He shot two people. If it turns out that he is the one who brought the gun to the scene, I don’t see how a jury could find him not guilty. You don’t get to shoot people, no matter how annoying, crazy, and manipulative they may be.
Time served seems light, but given the fact nobody actually died, maybe? I don’t know what the mandatory minimums are for attempt murder or lesser charges like assault with a deadly weapon but I’m guessing they are more than the 2 years he has already served.
