A beloved figure in New York City’s art world is at the center of a bizarre saga in which friends allege she is essentially being held captive in her own Manhattan home by her daughter. Concerns for 88-year-old Marie-Christophe de Menil’s safety were raised in a lawsuit filed earlier this month by a woman who says she worked for years as the philanthropist’s assistant and caregiver only to be falsely accused of trespassing at the home by Menil’s daughter, Taya Thurman, the half-sister of actress Uma Thurman. Alina Morini says her arrest was “planned” by Taya Thurman, who she alleges is subjecting de Menil to a “forced and ongoing isolation,” the New York Post reports. “I get calls from people close to her. They say they are cut off and concerned,” Robert Hantman, an attorney representing Morini, told the Post.
