WICHITA, Kan. (AP) — A chimpanzee housed for more than 17 years at the Wichita, Kansas, zoo has died at the age of 44.

Sedgwick County Zoo officials say the chimp named Tammy died Sunday after several days of failing health. A post-mortem examination is planned.

The animal was diagnosed in February of last year with heart disease and had her right arm amputated because it had become dislocated and unfixable.

Tammy had been at the zoo since early 1999.

The zoo still has seven chimpanzees.
