Summary based on the NamUs case record (MP9104) and 3 other sources
Charles Franklin Hoekstra, a 43-year-old man, went missing on December 9, 1993, in Rowlett, Texas. He was last seen leaving for work at the Superconducting Super Collider facility, where he was employed as a structural engineer. Hoekstra never arrived at his workplace, and this marked the beginning of a mystery that remains unsolved to this day.

The day after his disappearance, his vehicle, a red 1986 GMC Jimmy, was found abandoned on a service road off of Interstate 20 in Dallas. Despite the discovery of his car, there has been no trace of Hoekstra himself. He was wearing a white dress shirt, jeans, a denim jacket, and white Reebok sneakers at the time he was last seen. He also had on a gold watch and a wedding band. Known to wear eyeglasses or contact lenses, Hoekstra also had several scars on his body, including his abdomen, back, and ankles.

Foul play is suspected in Hoekstra's case due to the mysterious circumstances surrounding the discovery of his abandoned vehicle and the lack of any subsequent communication from him. Despite investigations by the Rowlett Police Department and efforts by various missing persons organizations, no substantial leads have emerged to explain his sudden disappearance.

This case remains open, and Hoekstra's family and investigators continue to hope for new information that could shed light on his fate. Anyone with potential information is encouraged to contact authorities.
