Yun Cha Dainiak was 23 when she disappeared from Harker Heights, Texas, on January 24, 1987. Witnesses reported seeing two unidentified white males assault her in the early morning hours, force her into an older model green two-door vehicle, and drive away. She has not been seen or heard from since.

At the time of the abduction she was wearing a white kimono-style coat, a red blouse, and red leather pants. Local law enforcement, including the Harker Heights Police Department, investigated but the case produced very few leads and remains open. Authorities continue to classify the incident as an abduction and are seeking tips that could help locate her or explain what happened.

If anyone was in Harker Heights on January 24, 1987, or remembers seeing that vehicle or the two men, please contact the Harker Heights Police Department with any information.
