Diane Yates, 46, vanished from her family’s home in Ontario and was last seen on October 28, 2002. A tourist later found her purse and glasses near the edge of the Niagara River, which flows into Niagara Falls. Earlier that month she had traveled to Niagara Falls intending to take her own life but did not on that occasion.

Investigators, aware of Diane’s long history of debilitating mental health problems, concluded the most likely explanation is that she died by suicide on the day she went missing. Her body has never been recovered from the river, leaving her family without physical closure.

If anyone saw Diane in late October 2002 or remembers unusual activity near the Niagara River that day, please come forward with information.
