Kristina Thay Nguyen was four years old when she disappeared from Cincinnati, Ohio, with her mother, Van Stephanie Nguyen, and her younger brother John. The last confirmed sighting of the family was April 18, 2002. Stephanie left notes that day expressing despair and saying she planned to take her own life and the lives of her children by driving into the Ohio River.

On April 19, 2002, a police officer stopped Stephanie’s green 1997 Nissan Pathfinder near a boat ramp to the Ohio River and saw two children believed to be Kristina and John asleep in the back seat. After that stop the family vanished. In October 2021 investigators located the submerged Pathfinder in the Ohio River near Aurora, Indiana; a human bone recovered from the vehicle was later identified in January 2022 as belonging to Stephanie Nguyen. There was no sign of Kristina or John in the recovered vehicle and both children remain missing.

Does anyone have verifiable information about Kristina or John’s whereabouts in April 2002 or afterward?
