Katherine Elisabeth Berry, 20, vanished from Muskogee, Oklahoma in early 1989. A Caucasian woman with brown hair, she was between 5 feet 3 inches and 5 feet 5 inches tall and about 115 to 125 pounds. The exact date of last contact and what she was wearing are unknown, and the circumstances of her disappearance remain unclear.

For decades no police report existed; Katherine’s younger sister Natalie—an infant when Katherine went missing—learned of the case as a teen and filed an official missing person report on March 25, 2023, reopening the investigation. Family memory gives an alternate possible last-seen timeframe around February 1987. Katherine’s mother and half-sister have submitted DNA for comparison against unidentified remains databases, with no match so far.

If anyone knew Katherine, her habits, friends, or where she spent time in Muskogee in the late 1980s, can you share information?
