I think that there are some very clear signs that Te'o was intentionally lying -- not being a naive victim of a hoax -- throughout the entire scheme.
This was posted very early in the the thread, but if you haven't listed to
Jim Rome's October 2012 interview with Te'o, I think it is very telling, specifically at the 5:30 point:
Jim Rome: Tell me about her. What was she like?
Manti Te'o: Man...if....she......I can't describe her.
I read Te'o's reaction as if he is just struggling to invent something to say about his imaginary girlfriend.
Then, in the September 2012 interview with SI's Pete Thamel, the following exchange occurs:
SI: When did you start talking to her all night?
TE'O: When she got in her accident.
SI: So starting in April?
TE'O: Yeah and you know, she was in a coma. I would try, and you know.
SI: Hit by a drunk driver. What were her injuries?
TE'O: I don't know. She had a lot of different injuries.
SI: How long was she hospitalized?
TE'O: She was in that hospital for about two months.
SI: Wow, did she get out?
TE'O: She didn't get out. She went from there. Remember she got in the accident and she was in a coma. We lost her, actually, twice. She flatlined twice. They revived her twice. It was just a trippy situation. It was a day I was flying home from South Bend to go home for summer break. It was May. Mid-May. That was the day where they said, "Bro, we're going to pull it. We're going to pull the plug."
How would Te'o not know what injuries his girlfriend had if he spent all this time talking to her? That never came up in conversation when he was spending all these nights talking to her? If he actually had any relationship with a person who was faking being injured to the extent that they were talking of "pulling the plug" on her, I can assure you that Te'o would have been able to answer the question about what injuries she had better than a "I don't know" response. Also, when discussing his "girlfriend" in the SI interview:
SI: What did she do?
TE'O: She actually just graduated from Stanford. She worked at Clark's Construction Company, I think. She replaced her dad after her dad passed.
SI: When did her dad pass?
TE'O: In October. She took that mantle for him.
SI: Does the family own a construction business?
TE'O: No. But they're part of the whole administration, the higher-ups. Their family worked really hard and worked their way up.
.....
SI: What did she study?
TE'O: She graduated in 2011 or 2010. 2011.
SI: What was her major?
TE'O: Her major was in English and something. I'll double check.
So, despite talking to her for hours on the phone every night, Te'o is not entirely sure where she works (although he later goes into great detail about how she took her dad's position after he passed); he is not sure when she graduated from college; and he does not know her majors. You would think that there would not be any hesitation to answer those questions if he had been "duped" by someone who made up things to tell him. Instead, Te'o seems as if he is just making stuff up spontaneously off of the top of his head or trying to remember what he said before.Another thing that I found striking from the SI interview is the way in which Te'o describes his "girlfriend" in that interview.
SI: How do you want her to be remembered?
TE'O: Lennay was so special. Her relationship with the heavenly father was so strong. She's so humble, hard working. And her main thing was her family. Her family was everything to her. As long as she took care of her family. And as long as she knew that her relationship with our heavenly father was strong, she had faith that everyone would work out. With her it was just always loving God and her family. I was just blessed to be part of that.
So, his "girlfriend" was very religious and her family meant everything to her. Sounds strikingly similar to Ronaiah Tuiasosopo, who lives in the same town as his family, plays Christian music in the church where is dad is a pastor, and posts religious music on YouTube. Oh, and don't forget that Tuiasosopo was also in a car accident shortly before Te'o "girlfriend" was.
My sense just tells me that Te'o's responses in these interviews were those of someone who was intentionally lying to hide a bigger secret -- not someone who was naively duped into believing a false tale.
