Diane Elizabeth Tresham was 51 when she was last seen in Niagara Falls, Ontario, on March 26, 2000.

There is no public information about Diane’s state of mind at the time of her disappearance or about a crime scene or witnesses that could form a clear narrative.

For Diane’s family and her community, the absence of answers has been a long-standing sorrow. Does anyone in the Niagara Falls area remember Diane or have information about where she was on or after March 26, 2000?
