So you think the Belizean police are digging up the heads --- just the heads --- of McAfee's dogs while he watches them disguised with shoe polish on his face?
No, they dug up the entire bodies, but only kept the heads, which is normal concidering it's a standard way to test for poisons in dead animals (they test the brain matter, not the muscle tissue).
Here it's worth noting that McAfee contests this explanation. There is some other, more sinister reason they've taken the heads of his dogs. I think we all know what it is.
