The son of late socialite Brooke Astor and one of her former lawyers have been indicted by a grand jury for stealing millions of dollars from the late philanthropist’s fortune during the last years of her life, the Manhattan district attorney said in a news conference today.

Anthony Marshall, 83, turned himself in at the Manhattan DA’s offices to face charges of fraud, forgery and grand larceny after it was reported yesterday that he and his former lawyer Francis Morrissey would be indicted for criminal activity over the handling of Astor’s will.

"I don't have a voice, my lawyer does," Marshall was quoted by Daily News as telling reporters as he arrived at the Manhattan district attorney's office in lower Manhattan shortly after 8 a.m. with his wife, Charlene, on his arm.

Morrissey was indicted on charges of forgery, criminal possession of a forged instrument, scheme to defraud and conspiracy.

"The indictment charges that Marshall and Morrissey took advantage of Mrs. Astor's diminished mental capacity in a scheme to defraud her and others out of millions of dollars," said District Attorney Robert Morgenthau, adding that Marshall abused his power of attorney and persuaded his mother to sell assets by falsely telling her that she was running out of money.

The indictment alleges that Marshall and Morrissey also induced Astor to change her will to make Marshall the sole heir, changing Astor's long-established plan to leave her fortune to charity.

According to reports, a year ago, Astor’s grandson and Marshall’s son, Philip Marshall, accused his father of transferring Astor’s properties to his name, stealing from her vast art collection and denying her medical treatment. The indictment comes as a result to the investigation conducted following the accusations.

Attorneys for Marshall issued a written statement on his behalf, saying "Tony Marshall faithfully and effectively managed his mother's affairs for more then 25 years, increasing the value of her investments from $19 million to $82 million. Brooke Astor loved Tony, her only child, and whatever he received was in accordance with her wishes. Just as the original claims of ‘elder abuse’ were found to have no basis, we're confident that once all the facts are known, Mr. Marshall will be exonerated."

The socialite, whose estate is valued at $132 million, in addition to a $60 million trust, died in August this year, at the age of 105.
