Ina M. Arnall, 46, left her Poteau, Oklahoma home on May 28, 1981, intending to drive more than 100 miles to Tulsa to visit her daughter but never arrived and has not been seen since. She was described as a stay-at-home mother of three, warm and dependable. At the time she vanished Ina was described as a Caucasian woman with brown hair and hazel eyes, between 4 feet 11 inches and 5 feet 2 inches, weighing 90 to 110 pounds, with stretch marks on her abdomen and full upper dentures.

The morning after she disappeared her 1980 diesel Oldsmobile was found locked in a Tulsa International Airport parking lot with her purse and personal belongings inside. Investigators reported no signs of a struggle or forensic evidence, and there were no known witnesses who saw her at the terminal. Early leads included unconfirmed theories that she might have gone to San Francisco or Nevada, theories her family disputes; others have suggested possible foul play tied to someone she planned to meet in Tulsa. The Oklahoma State Bureau of Investigation keeps the case active and asks anyone with information to come forward.

If anyone knew Ina, saw her car at the Tulsa airport that week, or has any information about her travel or contacts on May 28, 1981, please share what is known.
