Althedia Vernon Vaught, 42, disappeared from her Tulsa, Oklahoma home on the night of January 19, 2009. That evening she told family she was going to bed but around 11:30 p.m. took a phone call and promptly left the house with only her cell phone, still wearing pajamas and slippers. A heater and television were left on, suggesting she did not plan to be gone long.

On January 24, 2009, her dark green 1995 Infiniti was found abandoned in a parking garage at Hillcrest Hospital with no sign of Vaught or a struggle. Security footage showed a white 2003 Chevrolet extended cab pickup with a distinctive three-triangle insignia on both doors entered the garage about 35 minutes before Vaught’s car arrived and left after her vehicle was parked; police later interviewed the truck’s driver but have not publicly tied that vehicle to the disappearance. Her cell phone number was disconnected for six months, then later answered by a man who said he had bought the phone.

Investigators consider foul play a leading theory. If anyone knew Althedia, saw her car at Hillcrest Hospital in January 2009, or recognizes the three-triangle pickup, please come forward with information.
