Details of Disappearance
Stephanie disappeared from Cincinnati, Ohio on April 18, 2002. She left behind notes for her husband and parents saying her failed marriage had driven her to death and she was going to kill herself and her children by driving into the Ohio River near the Grand Victoria Casino. She disappeared along with her two children, Kristina and John.
The Nguyen family was last seen on April 19, the day after they left home, when a police officer stopped Stephanie in her car, a green 1997 Nissan Pathfinder with the Ohio license plate number ADH7739, near a boat ramp to the Ohio River. He stopped her for failing to dim her headlights. The officer noticed two children, presumably Kristina and John, asleep in the backseat of the vehicle. They were never seen again.
In October 2021, Stephanie's car was found in the Ohio River near Aurora, Indiana. There was a human bone inside the vehicle, and the bone was identified as Stephanie's in January 2022. There was no indication as to the whereabouts of either of the children, however, and it's not clear whether they were in fact in the car when it went into the river.
