Teague was last seen playing in the seventh-floor gallery of her family's apartment building at Robert Taylor Homes in Chicago, Illinois on June 25, 1983. She lived with her parents and three older brothers; her grandparents also lived in the building. The building was located in the 5000 block of south Federal Street; it has since been demolished.

Teague's parents left her in the care of her grandmother the evening of her disappearance while they went to a drive-in movie. They left at 9:00 p.m. An estimated 50 people were in the hallway at the time, including Teague's cousins, two aunts, her uncle and many neighbors. At 9:30 p.m., Teague's grandmother left her alone for a few minutes to answer a phone call. When she returned, the baby was gone. The police were called at 3:00 a.m., after Teague's parents returned home. Although the gallery was packed with people and there were only three exits, nobody saw anything suspicious.

Teague has never been heard from again. Investigators believe she was abducted by a non-family member.
