A great deal is made about footwear in the Sonia Varaschin case, relevant because it might be a key to the killer's occupation.
I wonder what occupation might a person wearing 3/4 sleeve shirt, size 17 might be?
I wonder if any new advances in DNA and collection of it, might find something inside the lock and key. What about the tape found.. duck tape was not as commonly used then as now...
I didn't even think about the types of tape that may have been used back then, or what that could indicate.
I was checking online and found the Canadian DNA Database was established in 2000 I believe. It made me wonder how many other possible cold cases may have been sent for forensic or DNA testing and which ones may not have been sent as of yet. I just have difficulty in believing the person only committed one heinous crime and never did so again. I do find it plausible they may have been spooked by the fact Sharron was found so quickly and moved on to another area, at least temporarily.
It also made me wonder about the exchange of information between countries, like Canada and US. I found an article that referenced a system to possibly help exchange genetic information. Based on the information in the blurb, I assumed the date of the article was 2009 or 2010.

I also found that an Interpol Global DNA Database has been established, several countries have actually exchanged information, and it appears to have met with pretty good success. It makes me curious as to what the possibilities could be, especially with countries that share borders. It made me think that two or more cases, relatively independent and seemingly unrelated on their own, that are found to be genetically linked, may each hold a clue for the other that could help solve the case or jump start a stalled investigation.
