Summary based on the NamUs case record (MP80933) and 3 other sources
Sonia (Sonja) Kay Redbird, a 19-year-old Native American woman, was last seen on January 1, 1975, in Dallas, Texas. Originally from Anadarko, Oklahoma, Sonia had relocated to Dallas in 1972. She remained in regular contact with her family until 1975, when all communication abruptly stopped. Sonia's family, concerned about her sudden disappearance, later had her legally declared deceased through the Kiowa Tribal Court.

At the time of her disappearance, Sonia was approximately 5'0" to 5'4" tall, weighing between 130 to 140 pounds, with brown hair and brown eyes. She was an enrolled member of the Kiowa Tribe. Despite extensive efforts by her family and authorities, including involvement from tribal and federal agencies, the circumstances surrounding Sonia's disappearance remain unclear.

Her case, classified as "endangered missing," is still open and unsolved. Investigators from the Kiowa Tribe, the Bureau of Indian Affairs, and local law enforcement continue to seek any information that could shed light on what happened to her. Despite being missing for nearly five decades, her case continues to be a focal point for those seeking justice for missing Indigenous women.

Last Seen: Jan 1, 1975
