Welcome to Websleuths
@11123findyou ! Do you know if your spouse's son already has a thread here? If not, and you'd like to start one, maybe we can help you start it. You'd need links from approved sources (RCMP links should be fine as a law enforcement source? Or links from approved missing persons websites such as namus or ncmec or doenetwork, or local news stations).
Also, if you'd like to post as an insider to the case, there is a process you can do to become a verified insider. This would allow you to post some information without including links. I'll find the link in a sec and add to this post.
Hope this helps!
