Stephen submitted an appeal. I'm assuming it's in regards to the sentencing, rather than the conviction. He would be stupid to appeal the conviction since it means it goes back to trial. I would love to take this back to trial since that would mean we would most likely get a better conviction. An appeal in regards to the sentence would take a while regardless, so he's stuck in jail until then... whenever that ends up being.
The funny part about all this is that his attorney has withdrawn from the case. Maybe he got tired of the BS that was SO obvious.
