A woman walking along Tara Boulevard was struck and killed by a piece of metal hanging from a truck Monday morning in Clayton County.

The 58-year-old woman, whose name has not been released, was in a grassy area and not in the roadway when she was struck, according to Officer Phong Nguyen with Clayton County police.

Investigators believe a fencing company's truck had a poorly secured pipe hanging off, and the metal struck the woman as the truck also traveled southbound, Nguyen said. The metal hit the woman in the back of the head, he said.

Charges are pending against the driver of the truck, Nguyen said.
