An Arizona girl who has been missing for nearly 30 years has been found alive in Springfield, Missouri, where she is now a married mother of three children, according to reports.

The woman, who disappeared in 1994 when she was a teenager, had been living under a different identity and was working for a private investigations firm in Missouri. The case had originally been treated as a kidnapping, but investigators have now discovered she had built what authorities describe as a "secret life."

Details about how the woman was initially reported missing or the circumstances of her disappearance in 1994 have not been released. It remains unclear whether she left voluntarily or was taken against her will at the time.

The discovery raises questions about the original investigation and how the woman was able to establish a new identity and life in another state for three decades without being detected by authorities.

Investigators have not released information about whether the woman wishes to reconnect with her original family or what led to her recent identification after so many years.
