Travis The Chimp, who starred in TV commercials for Old Navy and Coca-Cola, died on Monday. The nearly 200-pound chimpanzee was shot by Hartford, Conn. police after a violent attack on his owner’s friend.

According to the Associated Press, Sandra Herold, who owned the 15-year-old chimp, wrestled with the animal after he pounced on her friend Charla Nash, 55, in a unprovoked mauling that started after Charla tried to coax the pet back in her house.

“She retrieved a large butcher knife and stabbed her longtime pet numerous times in an effort to save her friend, who was really being brutally attacked,” said Stamford police Capt. Richard Conklin. The chimp, who was suffering from Lyme disease, went after some of the officers. One of them shot Travis, who later died of his wounds.

On Wednesday, officials released the frantic 911 tapes from the Connecticut chimp attack. Sharon is heard pleading for police to shoot her pet chimp while he attacked her close friend.
