Katie Waller was 15 when she was reported missing from Oklahoma City, Oklahoma, with a last-seen date of September 17, 2025. Public missing-child alerts identify her as female, American Indian, with black hair and brown eyes.

Available postings give few concrete facts beyond those identifiers and the last-seen date. Alerts do not specify where in Oklahoma City she was last seen, who she may have been with, what she was wearing, or whether investigators considered her disappearance voluntary or the result of foul play. A Stop Child Abuse alert remained posted after the disappearance and listed her age as 16, showing it was still active as time passed.

Anyone with information, however small, was asked to contact the National Center for Missing & Exploited Children at 1-800-843-5678 or the Oklahoma City Police Department at 1-405-231-2121. Does anyone have sightings, messages, or other details about Katie from around September 17, 2025?
