Katie Waller was 15 years old when she was reported missing from Oklahoma City, Oklahoma, with her last-seen date listed as September 17, 2025. Public missing-child alerts identify Katie as female, and the available online case details describe her as an American Indian girl with black hair and brown eyes. The same alerts list her as being missing from Oklahoma City, Oklahoma, in the United States, and they place the beginning of the public search around that September 17, 2025 date.
The online information available about Katie’s disappearance is limited, and that absence of detail leaves much of the story painfully incomplete. The public alerts do not describe the precise circumstances of where she was last seen in Oklahoma City, who she may have been with, what she was wearing, or whether investigators believe she left voluntarily, was taken, or encountered some other danger. What is clear from the available postings is that Katie’s case was treated as a missing-child matter, with her name, photograph, identifying details, and last-seen information circulated so the public could help bring attention to her disappearance.
Katie’s listed physical identifiers are among the few concrete details made public: she is described as female, American Indian, with black hair and brown eyes. Stop Child Abuse’s missing-child alert listed her current age as 16 while also tying the missing date to September 17, 2025, indicating that the alert had remained posted after time had passed from the original disappearance. The alert also asked anyone with information, even information that might seem small, to come forward because a minor detail could help investigators understand what happened after Katie was last seen.
The public call for help directed tips to the National Center for Missing & Exploited Children at 1-800-843-5678 and to the Oklahoma City Police Department at 1-405-231-2121. Those contact points matter because cases involving missing children often depend on people sharing sightings, communications, social media activity, transportation details, or observations that may not seem important at first. In Katie’s case, the online sources do not provide a fuller timeline beyond the last-seen date and location, so the available record remains centered on a 15-year-old girl, last seen in Oklahoma City on September 17, 2025, whose identifying details were released publicly in hopes that someone would recognize her, remember something, and help answer where she went after that day.Last Seen: Sep 17, 2025
