Serves him right for trying to steal the intelligent monkeys’ dried firewood.
Or, perhaps much more likely, the 72 year old was murdered by one or more humans who then came up with the ludicrous claim “the monkeys did it” similar to “the dingoes stole my baby” explanation of lore.
We had monkeys in the backyard in Nairobi, who would sit in the top of an avocado tree and throw avocados as the dog. The dog would get so filed up he would try to climb the tree after than. As soon as he was about ten feet off the ground, a monkey would hit him square in the face with an avacado, causing him to call down.
The monkeys thought this was hilarious. They did the same thing every day.
