His brother's profiles were instrumental in connecting the dots.
It basically went like this: His name was leaked on lolcow > found his instagram and Steam (from the twitter username) > found his brother through his instagram > found his hometown through his brother, which is also listed on Steam > found his facebook through his brother's > his facebook has links to his hometown, Chris, and Texas Tech. There are links to Chris and Texas Tech on his Twitter and Instagram too.
Oh, and the dog (same one that Kelly gave away, see OP) is his brother's facebook profile pic.
Hopefully that clears things up.
