"One shot in the head and he just went under." With that, great-grandmother Judy Cochran had the makings for a pair of alligator boots, or perhaps a closet full of them. "Don't mess with Nana," says Cochran, mayor of Livingston, Texas, where she snagged a 12-foot, 580-pound gator at her family's ranch along the Trinity River during a 20-day hunting season, per KTRK. Suspecting the animal killed her miniature horse three years ago, she plans to eat the meat and mount the "humongous" head in her office, reports USA Today, noting Cochran's grandson killed a 12.5-foot, 800-pound gator in the same area in 2009. He was then only 5. (More alligator stories.)
