GARFIELD, N.J. -- An 80-year-old woman was mauled to death by two pit bull dogs that she had known since they were puppies, Bergen County authorities said Tuesday. Wounds caused by claws or teeth covered more than 80 percent of Julia Mazziotto's body, and the medical examiner found she had also suffered a broken right wrist, county Prosecutor John L. Molinelli said. Blood soaked her clothing and was spattered on the walls and floor of her apartment, he said.
