He was just convicted of a crime that could send him to prison for a quarter century, but the troubles of the 85-year-old son of philanthropist Brooke Astor don't end there. After the six-month trial finally concluded Thursday, Anthony Marshall found himself owing his legal team $4.7 million in fees, and he has yet to pay up, reports the New York Post. That sum could as much as double as the appeals process drags on. Marshall's wife, Charlene, is signed on as the debt's guarantor, which means that if the ailing Marshall dies, his lawyers could come after her. "She didn't have to agree to do that, but she wanted to help her husband," the source close to the case said.
