Investigators dangling a search warrant swarmed Michael Jackson's Neverland Ranch today as part of an ongoing criminal investigation. The purpose of the search was not disclosed, but Court TV reports that that a 13-year-old boy has brought allegations against the 45-year-old pop star. It was a decade ago that Jackson faced a child-molestation investigation; that case was eventually settled out of court. Ironically, the news comes on the same day Jackson's greatest hits collection, Number Ones, arrives in stores. What's more, CBS is scheduled to air a special on the Gloved One next Wednesday. A network rep says it's "premature to speculate" whether today's events will alter their plans. Worse case scenario, they can just foist the special on Showtime.
