A hunter was found not guilty Wednesday of manslaughter charges in the death of a woman he shot and killed when he mistook her for a deer.

A Penobscot County Superior Court jury returned its verdict Wednesday morning after a total of nine hours of deliberations.Donald Rogerson, a supermarket produce manager, was charged in the Nov. 15, 1988, death of Karen Wood, a 37-year-old mother of twin 1-year-old girls. She was shot once in the chest while she stood about 130 feet behind her home in Hermon, a Bangor suburb.

The 47-year-old Rogerson, the lone defense witness, testified Tuesday that he saw a deer in the scope of his rifle and fired twice before discovering he had shot and killed Wood.
