This is alleged to be a voicemail left by “Lennay Kukua” (who we now are told is really a dude pretending to be the Notre Dame football player’s fake girlfriend) on Manti Te’o’s phone, which first appeared on Katie Couric’s website.
Update: Katie Couric’s website has pulled the audio down after originally hosting the three mp3 files this morning, so the above link is 404-ing. Hm.
Update 2: TMZ has them. This is weird.
Update 3: They’re back on Katie’s website. Looks like some web producer just wanted to make them video files instead of mp3’s. OK, let’s move on.
