A Detroit Police Department detective is investigating
a string of gas station robberies in which a male with a handgun threatens
employees before fleeing with cash. The commonality to the robberies
is that the man always wears a Milwaukee Brewers baseball cap and a
black jacket.
The detective searches N DEx for the phrases " Milwaukee
Brewers” and
the words “jacket”, “cap”, “hat”,
or “ball cap.” N DEx returned too many results for effective
analysis so the detective refined the search to specify a geographical
area, Michigan and neighboring states. N DEx locates a file about an
FBI investigation in Chicago into a serial bank robber who wears a
Milwaukee Brewers cap.
