What Happened to Greg Fall's Dogs?

Greg fall was found dead from a gunshot wound to the head in his house. Some people have suspected that John McAfee himself says that he doesn't think fall poisoned his dogs. It's really hard to tell what happened. The dogs got sick and McAfee shot them all because they were sick. And if they were really poisoned, that's what you do to spare the dogs the pain. But Greg fall wound up dead and John McAfee is still the obvious suspect.
