'He's Ripping Her Apart,' Chimp Owner Screams on 911 Call

"He's killing my girlfriend! He's eating her!" the frantic owner of a chimpanzee screamed in a call to police as the animal viciously attacked her friend. "You have to shoot him!" the Connecticut woman tells the dispatcher in a chilling tape of the call as the crazed animal's screeches are heard in the background, reports the New York Daily News.

The victim was so disfigured that arriving police mistook her for a man, telling the dispatcher: "He's got no face." The woman, who had come to the house to help recapture the chimp after it had slipped out the door, has undergone surgery for her severe injuries. The chimp's owner slipped the animal a Xanax earlier in the day after it was acting "rambunctious," said a police spokesman. Some experts believe the drug may have triggered the violence.
