The son of philanthropist and socialite Brooke Astor surrendered Friday to begin serving a prison sentence for stealing millions from his aging mother.
Anthony Marshall, 89, turned himself in Friday after an appeals court turned down a request for bail pending further appeals.
His lawyers said Marshall suffers from Parkinson's Disease and congestive heart failure and cannot take care of himself.
They said forcing him to go to prison is "senseless and cruel."
His wife said she is saddened by the court's decision.
"My heart has been ripped out of my body," she said.
Marshall maintains his innocence and has spent years appealing the case.
He is set to serve one to three years in prison.
