PRINCETON, Ky. (AP) — A Kentucky woman has died of what police say appeared to be a self-inflicted gunshot wound and another person was injured in a shooting at a ConAgra Foods plant.

Princeton police said in a news release Wednesday that 37-year-old Nellie Renee Nichols of Dawson Springs went to the factory to confront her mother and began firing from a semi-automatic pistol. Police said a male bystander suffered a hand injury not believed to be life-threatening from one of the shots.

Police said Nichols was pronounced dead at a local hospital.

A statement from ConAgra said the company is aware of "an incident" outside of its plant involving three people. The statement said the people were not employees and the plant has been secured. ConAgra said it is working with police.

According to its website, ConAgra Foods, Inc. produces packaged foods.
