Buffy Sue Mayo, also known as Buffy Harris or Buffy Mayo Harris, was 25 when she left the Tulsa home she shared with her husband on South Utica Avenue sometime between 1:00 and 2:00 a.m. on July 12, 1994, saying she was going to buy cigarettes. She never returned. Buffy was described as petite, about 5 feet 5 inches and 90–100 pounds, with brown hair, brown eyes, glasses, and a rose tattoo on her right shoulder.

Her husband was the last known person to see her and reported her missing that same day, and police entered her as missing in national databases. No confirmed sightings, weapon, crime scene, arrest, or public charge has been reported; advocacy sites and some records list July 12, 1994 as her presumed date of death and treat the case as a likely homicide.

Her disappearance is haunted by family tragedy: her mother, Monnita Sue Kern, was murdered years earlier. If anyone knew Buffy’s routines, the people she saw that night, or has information that could help, please contact the Tulsa Police Department’s Missing Person Unit.
