THORNDALE, Texas - A pack of six dogs mauled a 76-year-old woman to death as she worked in her yard, authorities said. Lillian Loraine Stiles was riding on a lawn mower in her front yard Saturday when she was confronted by the dogs, described as pit bull-rottweiler mixed breeds, said Milam County Sheriff Charlie West. Investigators think Stiles was attacked when she got off the mower and headed into her house. Stiles had severe bites over her entire body, and a man who tried to help her was bitten on one leg, authorities said. The dogs were found at the home of Stiles' neighbor, Jose Hernandez. The sheriff's department will send the findings of its investigation to the Milam County District Attorney's Office, which will decide if any criminal charges will be filed against Hernandez. Thorndale is located about 70 miles west of College Station.
