12 harrowing tales of wild animal attacks

On Feb. 16, 2009, a loveable chimpanzee named Travis — who had starred in Old Navy commercials — went on a brutal rampage and ripped a Connecticut woman's face off. Such stories of wild animals attacking humans aren't terribly uncommon, though — and in many cases, the animals involved in these incidents end up being put to death. Here are 12 cases of humans befriending wild animals, with wildly alarming consequences.
Carl Wiser loved buffalo. He raised them for years on his Tennessee farm. At the peak he had a herd of about 60 buffalo, but by August 2010 the 64-year-old had just four left — and he was planning to get rid of them.
On Aug. 9, something went horribly awry. Wiser was talking on the phone when he noticed one of his buffalo chasing his horses. When he tried to separate the animals, the buffalo attacked him. His wife heard him screaming and calling her name. She found him semi-conscious with the buffalo standing over him. He later died at the hospital.
On Feb. 16, 2009, Sandra Herold's pet chimpanzee Travis brutally attacked Charla Nash, a woman he knew well. The 200-pound, 14-year-old chimp had been acting "rambunctious" that day, so Herold had given him a dose of the anti-anxiety drug Xanax. As he relentlessly mauled her friend, Herold stabbed him with a chef's knife. Police ultimately shot the animal, and he died in his room in Herold's home in Stamford, Conn. About 15 months after her pet chimp attacked, Herold died alone and friendless of an aortic aneurysm in her Connecticut home at age 72.
