Beth Israel Medical Center milked reclusive copper heiress Huguette Clark for more than $13 million in fees, donations and even a priceless painting during her 20-year stay as a patient—and greedy executives angled for $125 million more, her relatives allege in shocking new court filings over Clark's estate.

He told a colleague her "potential has been overwhelming[ly] unrealized."
