A woman was killed Monday morning in an apparent alligator attack on Hilton Head Island, South Carolina, according to the Beaufort County Sheriff’s Office. Witnesses told investigators the woman was walking her dog near a lagoon about 9:30 a.m. when she was attacked and pulled underwater by the animal. Emergency responders found the woman’s body in the lagoon; she as identified her as Cassandra Cline, 45, of Hilton Head Island. An alligator believed responsible for the attack was found and killed at the scene, the sheriff’s office said. The attack happened off Wood Duck Road in Sea Pines Plantation. While alligator attacks on humans are rare, they are not unheard of in the Deep South. In June, a Florida woman walking her dogs was pulled into the water and killed by an alligator. An autopsy is being conducted at the Medical University of South Carolina to determine the cause of the death.
