Savannah courthouse suffers partial collapse.

Three construction workers were injured when part of an upper floor collapsed inside Savannah's 124-year-old federal courthouse, which has been undergoing extensive renovations for more than a year. The building is in the middle of a $75 million renovation scheduled for completion next year and has been essentially gutted on the inside. It's unclear why roughly 30 square feet of the floor collapsed. No courthouse personnel were inside.
