Huguette Clark, a reclusive multi-millionaire heiress, died in New York City on Tuesday. She was 104.

The copper heiress died at Beth Israel Medical Center where she lived in seclusion for 22 years after cutting herself off from friends and family, reports

She left behind a $500 million fortune, including a $100 million estate in Santa Barbara, a $23 million country home in Connecticut and a $100 million Fifth Avenue apartment.

In recent years, the management of her estate has come under scrutiny, and is under investigation by the Manhattan district attorney’s office.

Clark had refused visitors for years and didn’t want anyone, including family, to know her whereabouts, according to her lawyer Wallace Bock. She was so fiercely private that she was registered at the hospital under a fake name and even made one of her lawyers speak to her through a door.

Clark married once, but later divorced and had no children. The beneficiaries of her will have not been revealed.
