Catherine Frances Clampitt, 26, disappeared from Overland Park, Kansas, on June 15, 1987, after moving there earlier that year to live with her brother. Originally from Korea and adopted and raised in Texas, she had been rebuilding her life with her brother’s help while leaving her young son with their parents. She was hired to work for Equi-II, a management consulting firm owned by John Edward Robinson Sr., and vanished shortly after beginning employment there.

Robinson, later identified as a serial killer and convicted of multiple murders in 2002, is considered the prime suspect in Clampitt’s disappearance along with several other missing women. Remains of some victims were recovered in barrels on property linked to Robinson, but Clampitt’s body has never been found and no concrete evidence tying her fate to Robinson has been reported. Her case remains unsolved and she is presumed a victim; anyone with information about her last movements or employment in Overland Park in June 1987 is asked to come forward.
