Today WikiNews, who originally broke the story, said:
...a post made at 12:26 AM EDT Friday morning to the talk page of a Wikinews article headlined as the 'Death of Nancy Benoit rumour posted on Wikipedia hours prior to body being found', the user admitted to writing that Nancy Benoit was dead at the Wikipedia article page for Benoit came from information that was garnered from 'rumors and speculation online.' Freakishly, the post turned out to be true.
The IP Address of the individual making the apology was identical to that of the one who posted the Nancy Benoit rumor, a strong confirmation of the admission's authenticity. The lengthy apology was not signed, with the individual claiming, 'I am just an everyday individual who posted a wrongful remark at the time that received so much attention because it turned out to actually happen.'
