Knife-wielding gorilla shocks zoo visitors

Knife-wielding gorilla shocks zoo visitors:

"'He grabbed the knife exactly in the correct position and he smelled it and looked at it,' said Calgarian Joe Scheffler, who was at the zoo with his wife, Heike. 'A few seconds later, another gorilla came and he was very interested.

'He tried to get the knife, but the gorilla with the knife lifted the knife for his buddy....It seems to me that the gorilla with the knife was a little bit angry, and he lifted his hand with the knife.

'It was just a scene from a crime,' added Scheffler, whose wife snapped photos of the morning incident."
