Alabama Boy Kills 1,051-Pound Monster Pig, Bigger Than 'Hogzilla'. An 11-year-old Alabama boy used a pistol to kill a wild hog that just may be the biggest pig ever found. Jamison Stone's father says the hog his son killed weighed a 1,051 pounds and measured 9-feet-4 from the tip of its snout to the base of its tail. Think hams as big as car tires.
