Dena Viola McHan, 19, disappeared on December 6, 1981, after leaving a friend’s apartment in Sacramento and driving toward her home in Stockton in a canary-yellow 1974 Toyota Corolla. She was last seen in the early morning; at a gas station during the trip an attendant saw two men harassing her. When asked if she needed help she said she would be fine. Neither Dena nor her car has ever been found.

Dena was a student at San Joaquin Delta College. Family members and investigators describe her disappearance as highly unusual and suspect foul play. Private investigators have been involved and the case remains cold with no significant leads reported.

If anyone has information about Dena, her route that morning, or the two men seen at the gas station, please come forward.
