Yes, according to Deadspin:
Did you enjoy the uplifiting story, the tale of a man who responded to adversity by becoming one of the top players of the game? If so, stop reading.
Manti Te’o did lose his grandmother this past fall. Annette Santiago died on Sept. 11, 2012, at the age of 72, according to Social Security Administration records in Nexis. But there is no SSA record there of the death of Lennay Marie Kekua, that day or any other. Her passing, recounted so many times in the national media, produces no obituary or funeral announcement in Nexis, and no mention in the Stanford student newspaper.
Nor is there any report of a severe auto accident involving a Lennay Kekua. Background checks turn up nothing. The Stanford registrar’s office has no record that a Lennay Kekua ever enrolled. There is no record of her birth in the news. Outside of a few Twitter and Instagram accounts, there’s no online evidence that Lennay Kekua ever existed.
The photographs identified as Kekua—in online tributes and on TV news reports—are pictures from the social-media accounts of a 22-year-old California woman who is not named Lennay Kekua. She is not a Stanford graduate; she has not been in a severe car accident; and she does not have leukemia. And she has never met Manti Te’o.
The entire piece is a must read.
