Heather Dawn Park, 45, a member of the Cheyenne and Arapaho tribes, was fatally shot multiple times while sitting in her car at a Dino Mart convenience store in Arapaho, Oklahoma, on the evening of April 20, 2019, around 6:30 p.m. Her children were inside another vehicle just feet away. First responders took Heather to a hospital in Clinton and she was later airlifted to OU Medical Center in Oklahoma City, where she died of her injuries.

The person identified as responsible was her ex-husband, Brandon Benevento. He drove to the Clinton Police Department and surrendered shortly after the shooting. Court records show the couple had finalized their divorce months earlier and included multiple protective orders against Benevento. Investigators say the firearm found in his possession was consistent with the weapon used in the killing; he was arrested and charged with first-degree murder and reportedly told authorities he had blacked out during the incident.

Heather was a mother of five and a substitute teacher; her death had a profound effect on the small community. If anyone has information about Heather, her family, or the events that night, please share what is known.
