The 23-year-old marketing executive went to high school in California with Tuiasosopo, but she says they're not close. Tuiasosopo called to apologize the day Deadspin.com broke the hoax story, she said.
In an interview with ESPN last week, Te'o said he had received a Twitter message from Tuiasosopo apologizing for the hoax.
The Hawaiian also spoke to Tuiasosopo on the phone the day the Deadspin report came out, according to ESPN.com. He found out that "two guys and a girl are responsible for the whole thing," he said.
But he did not know the identities of the other individuals involved, other than the man he says was Tuiasosopo.
Tuiasosopo, a 22-year-old resident of California, has not admitted involvement publicly. Tuiasosopo graduated from Paraclete High School in Lancaster, Calif., in 2007 and has posted dozens of videos online singing Christian songs.
Those who knew him say he was a devout Christian and a good athlete. His former football coach Jon Flemming described him as gregarious, and from a "good loving family." Flemming said Tuiasosopo is the kind of guy who gives you a hug when he sees people he knows.
"He's doing good. Wishing everyone would go away," Flemming told ABC News Wednesday after a recent correspondence with Tuiasosopo.
Flemming said Tuiasosopo is "somebody I'd want my kid to grow up like. He's responsible, respectful, disciplined, dedicated."
Tessi Toluta'u, a Polynesian beauty queen, told ABC News this weekend that "Lennay Kekua" reached out to her in 2008 about entering pageants.
When visiting Los Angeles in 2009, Toluta'u was supposed to meet Kekua, but she failed to appear. Tuiasosopo met Toluta'u instead.
"[It's a] sick joke that went way too far," Toluta'u said.
