The owner of two pit bull dogs that ripped a woman to death in front of horrified onlookers was convicted Friday of criminally negligent homicide.

Edwin Hill, 44, a former policeman, faces up to two years in prison at his sentencing June 7, said prosecutor Don Strother.Prosecutors described the June 1990 death of teacher Betty Lou Stidham, 57, as being "eaten alive."

Stidham was attacked in a yard separating her residence and Hill's, police said. Ambulance attendants were held at bay by the dogs while the animals continued to tear at her body, trial witnesses said.

Police eventually ran the animals off by shooting and wounding one of them. The animals have since been destroyed.
