A 65-pound rabid beaver attacked two sisters at Virginia's Lake Anna, leaving them with serious injuries. Annabella and Alyssa Radnovich, ages 8 and 11, were swimming in the lake Sunday morning when the large rodent approached. “She could see this dark shadow underneath her, so she thought it was a person,” the girls' mother said. The beaver bit Alyssa as she tried to get out of the water, then went for Annabella. An uncle shot the animal with a BB gun, finally killing it with a hunting knife. One of the girls received stitches, but the other's injuries included muscle damage and could not be immediately closed due to infection risk. The police department took the animal for testing and confirmed it had rabies.
