Mayuko Kawase was a 21-year-old Japanese exchange student in Oklahoma City who disappeared in late August 2001. She was last seen by a classmate on August 20, 2001, and made a final known purchase at an Albertson’s on August 23. Family contact ceased after that period and she was reported missing on August 27; faxes piled up at her home suggested she had been gone for several days.

Nearly six years later, on April 14, 2007, boys hiking near Boy Scout Camp Kickapoo found a skull. Police recovery and forensic analysis indicated the remains were of an Asian or Hispanic female, 18 to 25 years old, deceased for two to ten years. DNA testing in August 2007 confirmed the remains were Mayuko’s, and the case was reclassified as a homicide. The skeletal remains did not permit determination of a cause of death. To date no suspects or arrests have been publicly identified and the investigation remains open.

Did anyone know Mayuko’s routines, classmates, or anyone she met in Oklahoma City in August 2001 who might have information?
