While visiting thier former chimp, Moe, on his 39th birthday. The Davises would soon get a birthday surprise of thier own. Buddy and Ollie (the 2 that attacked the man) broke out of thier steel cages and attacked the man, leaving his face severely raped, and his package ripped off. Dr. Maureen Martin of Kern Medical Center told KGET-TV of Bakersfield that the monkeys chewed most of Davis' face off and that he would require extensive surgery in an attempt to reattach his nose.
The 2 apes were shot on site by the owner. 2 others escaped also, and were both retrieved later.
