Searching news stories I have not see anything in the Chicago area in MSM about this. Its just kind of weird.
I don't think this would be Sergio. There are too many wooded areas closer to his home in Maywood to go that far north to harm himself.
Also, if he were to harm himself, I don't think he would return from out of the country to do so. Nor do I think he would choose hanging as a way to harm himself.
