The first indication that something had gone wrong down on the Ol' Thompson Farm was when one of his neighbors went outside to tend to his horses and saw a black bear slowly ambling toward him. He turned back to the house, at which point he ran right into a lion. After managing to escape and locking himself in a barn, the neighbor grabbed a phone and (as we all would) called his mom. The lady in turn called 911, which promptly sent a deputy ... to book somebody for making prank phone calls.
Within minutes of arriving, however, the deputy had shot a wolf, bear, and lioness with his rifle. With more and more animals swarming the area, he linked up with three other deputies and went a-hunting. After a while, they wound up at Thompson's farm and discovered the cause of the outbreak. Thompson, a troubled Vietnam vet with money problems, had bolt-cuttered the cages and then shot himself, but not before scattering raw chicken over his body in the hopes that it'd be eaten. He almost got his wish; in order to inspect the body, the law had to retreat until a white tiger was finished snacking on it.
The day went on, but without Thompson to give any precise figures on how many creatures he'd freed, the lawmen were left shooting in the dark -- quite literally. Unable to find a missing grizzly, they had to rope in a thermal imaging helicopter to track down its hiding place.
