Excerpt from Fox News:
An FBI spokesman, Dave Fitz, confirmed agents had gone to the upscale townhouse home. But he did not immediately release any other specifics, citing an ongoing investigation. The agents could be seen inside the home Sunday evening near Baltimore’s Inner Harbor. They wore bulletproof vests and carried long guns. Reporters who gathered outside did not see any authorities carrying any bags of evidence outside.
