From the AP:
"Prosecutors say [Marshall] falsely told Astor she was running out of money to persuade her to sell a Childe Hassam painting, 'Up the Avenue from 34th Street,' for $10 million; he allegedly took $2 million as a sales commission. He also is accused of taking two works of art, worth about $500,000 each, from Astor's house while she still lived there."
