One of Honolulu Zoo's oldest animals has died.

Cleopatra, known as Cleo, was the second oldest hippopotamus in captivity in the United States.

A zoo veterinarian put her to sleep on Saturday because she was suffering from growing complications of old age.

The 3,500-pound hippo could no longer stand on her own.

She was just a few weeks shy of her 53rd birthday. Zoo officials said the typical life span for a hippo is 35 years, but that animals in captivity sometimes live much longer.

Cleo will be sent to a university lab for research and study. The Honolulu Zoo has two other hippos.

MAN INDICTED IN WAIKIKI CHILD RAPE

A grand jury yesterday indicted a South Carolina man in the kidnapping and rape of a 10-year-old girl in Waikiki on Sept. 17.

Christopher Eugene Cantrell, 27, was charged with five counts of first-degree sex assault, and one count each of third-degree sex assault, kidnapping and promoting child abuse in the third-degree.

He was also charged with burglary and assault in the beating of the child's father.

He was being held on $200,000 bail.

Police said the attack happened at the ResortQuest at the Waikiki Banyan hotel shortly before 3 a.m., after the girl's father had befriended Cantrell and invited him to their 12th-floor room.

Once in the room, Cantrell allegedly attacked the girl's father and knocked him out. Police said Cantrell then kidnapped the girl and repeatedly raped her in a 10th-floor laundry room at the hotel.
