NEW YORK, Nov. 22 (UPI) -- Huguette Clark's estate sued New York's Beth Israel Medical Center for $100 million, alleging it secluded the heiress for two decades to get money from her.
The lawsuit, filed in Manhattan Surrogate's Court by the city public administrator, alleges the hospital kept the woman's stay at the hospital secret "in order to extract millions of dollars in 'rent' and 'gifts' from her."
Clark was initially hospitalized for skin cancer and malnourishment but stayed at Beth Israel until her 2011 death at the age of 104, the New York Daily News reported Thursday.
"All told, during Huguette's residency at Beth Israel, she made more than $40 million in 'gifts' to the hospital and her caregivers -- and paid millions of dollars in additional rent and fees," the filing said.
During her stay, the lawsuit alleges, the hospital "never provided any psychiatric evaluation or treatment to assess and treat any mental health condition, which led Huguette to the hospital in the first place."
The lawsuit also names Clark's primary physician, Dr. Henry Singman, who personally received close to $900,000 in gifts from the heiress, the report said.
The lawsuit alleges the hospital staff took pains to hide Clark's stay at the facility from its legal department and regulators, the newspaper said.
