Travis was a 13 year old, 200 pound male common chimpanzee who had various acting jobs and appearances in television commercials. Travis was well adapted and knew how to do many of the things we humans do on a daily basis. Travis however, held up the 'typical teenager' stereotype, as he was well known as a trickster and unfortunately well known to law enforcement.

On February 16, 2009, Travis attacked his owner Sandra Herold's friend Charla Nash, mauling her all over, inflicting devastating injuries to her face and limbs. The incident started when Travis "stole" Herold's car keys. As a friend of Herold and familiar face to Travis, Nash came over to help her friend coax the chimp back inside. Upon seeing Nash holding one of Travis's favorite toys, he immediately attacked her. Herold, then 70 years old, attempted to stop Travis by hitting him with a shovel and stabbing him with a butcher knife. The chimp only became more enraged. Herold then called 9-1-1 and pleaded for help. Initially the dispatcher thought the call to be a hoax, until Herold started screaming, "He's eating her!"

Emergency Medical Services waited for police to arrive before approaching. Travis walked up to the police car when it arrived and attempted to open a locked passenger door, and then smashed a side-view mirror. He then calmly went around to the driver's-side door and opened it, at which point Officer Frank Chiafari shot him several times. Travis retreated to the house, where he was found dead next to his cage.
