Sandra Lee-Anna Richardson, 39, was found dead and unclothed near the junction of Highways 62 and 48 in rural Okfuskee County, Oklahoma, on November 22, 2003. She had suffered severe physical trauma including a savage beating and two puncture wounds to her throat; the body’s location suggested the killer deliberately abandoned her to delay discovery.

Richardson had recently moved to Oklahoma City from Colorado and an email dated November 16 shows she had secured a new job and a place to live days before her death. Previously married and known by her maiden name Dillon, she was reported to have been involved in sex work, which investigators considered when exploring links to other killings of women found near truck stops.

Truck driver John Robert Williams was investigated after having at one point claimed responsibility for multiple highway killings, but he later recanted and authorities found no substantial evidence tying him to Richardson’s murder. No arrests have been made and the case remains unsolved.

If anyone knew Sandra, her movements in Oklahoma City that November, or saw anything near Highways 62 and 48, please share information with investigators.
