At a press conference following Marshall's arrest, Manhattan district attorney Robert M. Morgenthau stated 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." He further said that "Marshall abused his power of attorney and convinced Mrs. Astor to sell property by falsely telling her that she was running out of money. He is charged with stealing money from her as well as stealing valuable art work from her Park Avenue apartment."
