named executor and challenged Lafferty's appointment. Demopolous argued that Lafferty and his lawyers had cajoled a sick, sedated old woman into giving him control of her estate. Even more sensational accusations were made by a nurse, Tammy Payette, who contended that Lafferty and a prominent Beverly Hills physician, Dr. Charles Kivowitz, had conspired to hasten Duke's death with morphine and Demerol. In 1996, the year Lafferty died, the Los Angeles District Attorney's office ruled there was no firm evidence of foul play. Duke University also filed suit, claiming entitlement to a larger share of the Duke assets than the $10 million provided in the will, although Duke's will also stated that any beneficiary who disputed its provisions should receive nothing. Litigation involving 40 lawyers at 10 law firms tied up the Duke estate for nearly three years. New York courts ultimately removed Lafferty for using estate funds for his own support and U.S. Trust for failing "to do anything to stop him". The Surrogate Court of Manhattan overrode Duke's will and appointed new trustees from among those who had challenged it: Harry Demopoulos; J. Carter Brown (later also involved in overturning the will of Albert C. Barnes); Marion Oates Charles, the sole trustee from Duke's last will; James Gill, a lawyer; Nannerl O. Keohane, president of Duke University; and John J. Mack, president of Morgan Stanley. The fees for their lawsuits exceeded $10 million, and were paid by the Duke estate. These trustees now control all assets of the Doris Duke Charitable Foundation, which Doris Duke directed should support medical research, anti-vivisectionism, prevention of cruelty to children and animals, performance arts, wildlife, and ecology. The DDCF also controls funding for the three separate foundations created to operate Duke's former homes: the Doris Duke Foundation for Islamic Art, Duke Farms and Newport Restoration Foundation. The trustees have progressively reduced funding for these foundations, stating that Doris Duke's own works are "perpetuating the Duke family history of personal passions and conspicuous consumption." Subsequently, the foundations have sold some assets and have closed Duke Gardens. Auction house Christie's published a heavily-illustrated catalog of more than 600 pages for its auction of "The Doris Duke Collection, sold to benefit the Doris Duke Charitable Foundation", held in New York City over three days in 2004. The last living heirs to Duke's fortune are twins Georgia Inman and Walker "Patterson" Inman III, the children of Walker
