I think what we are missing here is whether or not the location of the 
ransom call is correlated with where the victim is being held, or where 
any of the kidnappers lives or did the planning. Without wishing to give 
anyone ideas, the objective here is to anonymise the location, or if not 
make sure it's "none of the above".
