A 2-year-old girl was found dead in a lake Saturday, and police believe that she may have been killed by an alligator. See The Story Alexandria Murphy was reported missing at 4:19 p.m. after she wandered away from her family's back yard, police said. Her mother and grandmother were inside the house when she disappeared. A Polk County sheriff's office deputy found the girl's body less than an hour later near the Lake Cannon shoreline. Alexandria had bites on both arms and her right thigh, as well as a broken left arm. The injuries are consistent with an alligator attack, State Fish and Wildlife Conservation Commission spokesman Gary Morse said. However, authorities were not sure if she drowned and was later bitten or vice versa. An autopsy was scheduled for Monday. An FWC trapper caught and killed the gator suspected in the attack. The reptile was 6 1/2 feet long, officials said. If the death is a result of an alligator attack, Alexandria would be the twelfth person to die in such an incident in the last 50 years. Last month, a 71-year-old Sarasota man was killed by an alligator.
