Woman still unidentified after 40 years
This case isn't listed on Hamilton Police's website, I found out about her here, actually.
Here is the original newspaper coverage of her discovery from the Hamilton Spectator on August 7, 1975.
The surprising thing for me about this woman is that she doesn't fit the bill of 'ignorable cases'--she was married, had nice clothing, jewelry with distinct markings and yet her identity is still a mystery. I find it odd, too, that I can't find any coverage on her regionally. Hopefully we can attain some photographs of her clothing and personal items to make it easier for someone to recognize and identify her.
Below is a map of the general region she was found.
