Manti Te'o, Lennay Kekua hoax timeline: Girlfriend hoax events, Tweets in chronological order

He added that Notre Dame did not plan to release the findings of its investigation.

"We had no idea of motive, and that was really significant to us. ... Was somebody trying to create an NCAA violation at the core of this? Was there somebody trying to impact the outcome of football games by manipulating the emotions of a key player? Was there an extortion request coming? When you match the lack of sort of detail we lacked until we got some help investigating it with the risk involved, it was clear to me until we knew more we had to just to continue to work to try to gather the facts," Swarbrick said.

The Deadspin report changed all that.

Friends and relatives of Ronaiah Tuiasosopo told Deadspin they believe he created Kekua. The website said Te'o and Tuiasosopo knew each other. Attempts by The Associated Press to reach Tuiasosopo by telephone were unsuccessful.

As for Kekua, Deadspin said she does not have a death certificate. Stanford, where she reportedly went to school, has no record of anybody by that name, the website said. Deadspin said a record search produced no obituary or funeral announcement. There is no record of her birth in the news.

There are a few Twitter and Instagram accounts registered to Lennay Kekua, but the website reported that photographs identified as Kekua online and in TV news reports are pictures from the social-media accounts of a 22-year-old California woman who is not named Lennay Kekua.

Te'o talked freely about their relationship after her supposed death and how much she meant to him.

In a story that appeared in The South Bend Tribune on Oct. 12, Manti's father, Brian, recounted an anecdote about how his son and Kekua met after Notre Dame had played at Stanford in 2009. Brian Te'o also told the newspaper that Kekua had visited Hawaii and met with his son. Brian Te'o told the AP in an interview in October that he and his wife had never met Manti's girlfriend but they had hoped to at the Wake Forest game in November. The father said he believed the relationship was just beginning to get serious when she died.

The Tribune released a statement saying: "At the Tribune, we are as stunned by these revelations as everyone else. Indeed, this season we reported the story of this fake girlfriend and her death as details were given to us by Te'o, members of his family and his coaches at Notre Dame."

The week before Notre Dame played Michigan State on Sept. 15, coach Brian Kelly told reporters when asked that Te'o's grandmother and a friend had died. He said Kekua had told Te'o not to miss a game if she died. The linebacker turned in one of his best performances of the season and his playing through heartache became a prominent theme during the Irish's undefeated regular season. He finished second in Heisman voting.

"It further pains me that the grief I felt and the sympathies expressed to me at the time of my grandmother's death in September were in any way deepened by what I believed to be another significant loss in my life," Te'o said in his statement.

"I am enormously grateful for the support of my family, friends and Notre Dame fans throughout this year. To think that I shared with them my happiness about my relationship and details that I thought to be true about her just makes me sick. I hope that people can understand how trying and confusing this whole experience has been."

Te'o and the Irish lost the title game to Alabama, 42-14 on Jan. 7. He has graduated and was set to begin preparing for the NFL combine and draft at the IMG Academy in Bradenton, Fla., this week.

"Fortunately, I have many wonderful things in my life," he said in his statement, "and I'm looking forward to putting this painful experience behind me as I focus on preparing for the NFL draft."
