Shannon Michelle Baldwin Hokanson, 29, of Enid, Oklahoma, was last heard from on May 27, 2012, when she made what became her final phone call. A mother of three, she was known for making consistent weekly calls to a family friend, and her sudden silence prompted growing concern. A family friend reported her missing on August 7, 2012, after weeks with no contact.

Shannon is described as a white female, brown hair and brown eyes, between 5 feet and 5 feet 3 inches tall and 120 to 150 pounds. Distinguishing tattoos include a frog with a mushroom on her ankle and a butterfly on the back of her right shoulder. Reports say she was last seen with two men; one of them was later found with her car but Shannon was not present. An acquaintance later alleged that one of the men confessed to dumping her body in a body of water across the Texas border, a claim authorities have not confirmed.

The Enid Police Department says they believe they know who was involved but have lacked sufficient evidence to file charges. The nearly four-month gap between Shannon’s last contact and the missing-person report has complicated the investigation. Did anyone in Enid or along the Texas border see Shannon or her car in late May or June 2012?
