NORTON – An off-duty state trooper who was hunting in Norton has shot and wounded a 66-year-old woman walking her two dogs after sunset, claiming that he mistook the tails of the retrievers for those of deer.

The woman was hit in the torso while walking on a wooded path at about 5 p.m. Saturday. Norton police say the trooper called 911 after realizing that his target was not a deer.

State police on Sunday said the trooper is not being identified because he faces no charges and no internal investigation.

The woman was taken to Rhode Island Hospital for treatment. Authorities did not immediately release additional information on her condition.

The woman is not being fully identified by police who said she and the trooper live in Norton.

State police say investigators have determined that the shooting was accidental.
