The Cell Site Location Information (CSLI), usually known as a cell dump should already be in the F.B.I.'s hands.
Because of the busy highway, I imagine there may be a huge amount of data for the investigators to go through but they may sort and prioritize local numbers to investigate first.

Do you think there would be a lot? I have driven from Rice Lake to Milwaukee many times. There is no traffic starting in Rice Lake. But further down,,much further down, 94 is the route to Chicago and there are tons of trucks.
I cannot remember when the traffic starts to get heavier. But it was late on Sunday night
