Item: the governor's armored SUV is found in the parking lot of the Columbia, SC airport. A sleeping bag is inside. (H/T, Peter Hamby.)
Item: Numerous media outlets cite a "federal agent" who saw Sanford at an airport in Atlanta, which matches a report that his cell phone was last tracked on a cell tower in Atlanta. (Fact hidden in that sentence: some law enforcement entity was worried enough to convince the cell phone company to part with its cell data.)
Item: His staff provides conflicting information about whether his cell phone was turned off, and on, and whether he gave anyone a detailed description of his itinerary.
Item: He's back in Columbia tomorrow, so... we'll know.
