The gorillas parents are Charles and from the Toronto Zoo... since Josephine cannot produce milk, the gorilla was hand fed. So I think there is a lot more than simply the gorilla escaping .... the door had to be unlocked... besides its not like gorillas to go nuts .... typically when they escape, they quickly go back into the comforts of their cage. I do fully blame the police for killing the gorilla, however, the zoo should have reacted much faster to ensure the gorilla was tranquilized ... its all based on opinion
