Stop telling us what you think and how believable he was and get to the facts.
This is pretty easy to determine if this was a hoax or not - did you ask Te'o for phone records? If he faked this whole thing, he wouldn't have been talking to a woman for hours on end. If he was duped like he says he was, the phone records would back it up. There should be no doubt.
If it was a hoax, did you ask him who the woman was?
Did you ask him why he never went to see this woman when she was in the hospital?
Te'o was smart to do this - right when Lance was speaking.
