We don't know for sure that it is more than one; didn't Ted Bundy cross the country in his killing sprees? It would be interesting to know WHICH OTHER parts of the country are being searched. If it's only 4 spots, it could indeed be one wandering nut.

I REALLY want to believe it's a lone nut who wandered the country killing people. I can't tell you how scared I got when I heard they were serving search warrants around the country. Associated Press is reporting FBI agents are searching the backyard of a duplex and it's related to the sniper killings.
