Sad ending to a story about a chimp who went nuts all of a sudden and viciously attacked it's owner's friend:

This is a sad story, both from the victim's view point and the ape's view point as well. I maybe wrong, but I don't think they should have been giving that ape any drugs. No telling what went wrong with him, and if the drugs were a factor in that, or not.
The chimp had seemed to have led a very productive life before all this.
