From a SB Tribune story...
The investigation ordered by Notre Dame was limited to the electronic search, Brown said. Investigators did not interview Te’o or his family, nor did anyone attempt to contact Ronaiah Tuiasosopo or any of his relatives.
In response to questions, university officials said the investigators did not examine cell phone records, e-mails or other electronic communication to determine the length or extent of Te’o’s
communication over the past few years with the person claiming to be Lennay Kekua, nor did the university ask Te’o to take a lie detector test.
