(CBS/AP) NEW YORK - Anthony Marshall, an 89-year-old heir to one of America's earliest mega-fortunes, has been granted medical parole after serving two months in a New York prison. He was convicted of siphoning millions of dollars from his mentally failing mother, Brooke Astor.
A parole board announced its decision Thursday in Marshall's case. It interviewed him Wednesday.
State law allows medical parole for inmates with serious and permanent illnesses.
Marshall's doctors have said he suffers from Parkinson's disease, depends on a wheelchair and can't do many daily tasks without help.
He began serving his one- to three-year sentence in June, after fighting his conviction for years.
Astor was a noted philanthropist in New York City.
She inherited a fortune from her third husband. He was a descendant of one of the nation's first multimillionaires, John Jacob Astor.
