An elderly woman in South Carolina was killed by an alligator Tuesday morning, police say.

The Beaufort County Sheriff's Office said the 69-year-old woman was found unresponsive near the edge of a lagoon in the Spanish Wells community of Hilton Head Island at around 9:30 a.m.

"Rescue efforts were made and an alligator appeared and was guarding the woman, interrupting emergency efforts," the sheriff's office explained. 

"The gator was safely removed from the area and the woman’s body was recovered."

According to authorities, this is the second local fatality involving alligators over the past year. An 88-year-old Sun City resident was killed by one near a lagoon last August.
