Deputies arrived to find Rollins dead with multiple injuries. Because there were different sizes of bites on her body, investigators think multiple hogs attacked her, Hawthorne said.
"This is a very rare incident," the sheriff said, adding that the coroner said Rollins bled to death after the attack by feral hogs.
Experts say that attacks on humans by feral hogs are rare, and fatalities even rarer. A 2013 study by John J. Mayer of the Savannah River National Laboratory looked at attacks by wild pigs around the world from 1825 to 2012. The study found only four fatal attacks in the U.S., and three of those were from animals that were wounded while being hunted.
