There was no plea deal. From the article:
"They each pleaded guilty to one misdemeanor count that carries a maximum possible penalty of a $10,000 fine and five years in prison. The judge said there was no agreement on the sentence they will received.
"There is no provision of the agreement that would limit my ability to impose sentence as I see fit," Boccabella said."
Judges will say this all the time. There's not a plea deal I ever worked where the judge didn't articulate to the defendant at the plea what the maximum sentence is and that there are no promises other than what charges he'll plea to. This despite us just agreeing to the sentence in chambers and the defense attorney checking with his client to make sure that's ok. The judge does retain discretion to sentence the person as he/she pleases, so it isn't untrue. But he/she always sticks to the original agreement.
