As the dust settles after Sunday's murder of the Alpha male we are still in a mild state of shock. The brutal side of Chimpanzee behavior is something that we have seen before and has been well documented but it’s hard to believe that they could go to such an extreme. Even after Pimu had passed away Kalunde repeatedly smashed a large stone into his head.
You can see the ruthless aggression in Orion’s face.
Pimu looks dazed and blooded after the first assault, unfortunately for him there was more to come.
