Seventeen-year-old Lisa Marie Gaskin was walking along the railroad tracks in the 4200 block of Southwest Boulevard in Tulsa, Oklahoma, on the night of March 28, 2000. She had visited her father at his workplace earlier that evening and at about 11:30 p.m. was seen with an unknown individual before she was brutally attacked. The assailant struck her in the head with a heavy, sharp object, dragged her to a nearby ditch, and strangled her; her body was discovered later that night.

A witness reported seeing the suspect flee to the northeast. No arrests have ever been made, and the case is now cold.

If anyone remembers seeing someone near the railroad tracks that night or has other information that could help, please come forward.
