Please realize that it's relatively trivial for someone playing a long con to use another person's identity. Consequently: don't do anything rash. Please act through the authorities or at the very least act under the assumption that you don't know where the real culprit is. 'Trendon Shavers' or whatever your dox results are is just the starting point. If he is also a particularly stupid con man, he's your endpoint too... but I doubts it.
Exactly. There are even darknet forums dedicated to identity theft and identity trading. Even if you've seen him face to face and he's shown a real passport with a photo that matches his face, it does not mean he is who he says he is.
