There was a tiny bit of information found on websleuth's.com indicating that two years before Lynda's body was found in 1973, that her wallet, containing her driver's license was found on June 25th 1971 by a construction worker digging a factory foundation. This was in Burlington, whereas her body, as noted elsewhere was found near Simcoe. Quite odd.
There are a few other jots & threads regarding this case, including some information from a fellow student and friend of Lynda's at UWO, mixed in with the posts for Jacqueline English (London, Ontario). I guess because she was last seen in London the potential linkages to other women abducted in London at this time are relevant.
