STAMFORD - The owner of a Stamford chimpanzee that mauled a woman last year has died.

An attorney for Sandra Herold says she died last night after she had a ruptured aortic aneurysm.

Herold was the owner of Travis the chimp, who mauled her friend Charla Nash in February 2009 at Herold's home. The animal ripped off Nash's hands, nose, lips and eyelids.

Nash's family is suing Herold for $50 million for injuries she suffered in the attack.

Herold was 72 years old.
