The fact that nobody seems to have seen TomKat's baby, Suri, leads me to believe any number of things. Perhaps this is simply a celebrity couple, very protective of their young, innocent child from the media and are therefore now fiercely guarding her identity. Or maybe it's a wacky alien love-child, being held captive by a crazy, celebrity cult in some strange kind of baby-prison.
Since it's always more fun to speculate than be sensible, I'm going to go with the baby-prison theory and throw in a quote from US Weekly for good measure:
Us, in a three-page spread, says a couple of Telluride locals have reported Suri spottings, including a clerk at a natural-goods store, who said Suri is "funny looking."

By "funny-looking," the clerk meant, "Tom and Katie's 'biological' child eerily resembles a nine-month-old Korean adoptee."
