If you really want to contact him, it sounds like you are curious. You really want to know more about the guy, not a bad thing at all.
I have some words of advice, rather simple and general but still important. Most of the facts you know about this guy are uncorroborated, you do not really have the luxury of putting his statements into context. Yes, the internet is a conduit for the deviants, but it is also a conduit for those with self esteem problems and those that like to embellish the facts a little, if you can get away with it why not. Act on your curiosity by all means, but remember always stay objective.
