A member of the Philippine Center for Investigative Journalism (PCIJ), Mr. Alecks Pabico, tried to do what the Manila Times should have done and researched the "UP Math prof proves Princeton man wrong" story.
First, He found out that the supposed e-mail from Andrew Wiles, was written on the guestbook of Mr. Escultura's website. I found it on page 5, of the guestbook. On page 4, another or the same person claiming to be Andrew Wiles wrote "You do, of course, realize I was joking, right? I mean about FLT. Apparently, you're the only one who took the whole thing seriously."
Second, He tracked down a contact address of Mr. Andrew Wiles, and and asked him to comment on the claims made by the Manila Times story. Mr. Wiles denies e-mailing or even of knowing the Mr. Escultura's website.
Third, He interviewed Mr. Escultura and got him to agree that some of the details from the story were wrong.
