A woman was mauled to death by her own dogs, and there are still many questions surrounding the case, an expert says.

According to Richmond, Va., CBS affiliate WTVR, Bethany Stephens' body was found by her father in a field in Goochland County.

“There were various articles of clothing, underclothing scattered about the area not far from the body and torn into small pieces, there were patches of blood,” Goochland Sheriff James Agnew told WTVR.

The sheriff said that according to a preliminary report from the medical examiner, Stephens' two pit bulls, each weighing about the same amount as her, 125 pounds, killed their owner.

A man who worked with Stephens at a dog-training facility told WTVR that she was experienced working with animals and loved her dogs.

And Dr. Amy Learn, a veterinarian who didn't know Stephens or her dogs, said many questions remain.

“I think the investigation needs to be ongoing,” she said. “Dogs don’t typically just out of the blue attack their owners, so there is typically some kind of provocation.”

The dogs are set to be euthanized.
