Subway ad slasher Poster Boy is back in the news (just in time for his book release!). According to the NY Post, the 28-year-old Henry Matyjewicz dodged jail time thanks to an oversight by Justice Michael Gary. Last year the street artist negotiated a probation deal with the DA, which evaporated when he was arrested again soon after. But yesterday Gary told the court that he had neglected to warn Matyjewicz that if he got arrested again the deal would be off. So he goes free! And he didn't even show up to court to hear the good news himself. His lawyer told the paper, "It should have been a happy day for him, but he wasn't there."
