WLS-TV in Chicago reports this afternoon the FBI has served search warrants at the Northern California offices of Yahoo and Google in connection with the Erin Andrews nude peephole video case.

One of the items they want from Yahoo is a video of another naked woman posted in June to flickr.com. Investigators believe the flickr.com account belongs to 48-year-old Michael Barrett of Westmont.

So the Feds think Michael Barrett was uploading video of another naked woman?

Barrett has pleaded not guilty to one count of interstate stalking, and faces a mere max of five years in prison. It sounds like the FBI is determined to find more incriminating activity at the (filthy) hands of Barrett.
