Morphology of Where in the World is Carmen Sandiego?

Computer

At any time, the player can enter information about the suspect into a crime computer. The crime computer will match the data given to a list of known members of Carmen's gang. Each time the computer is used, it will give the player a list of all the suspects that match the data entered.

The computer will give you a warrant to arrest the criminal once you have collected enough information to narrow down the list of suspects to just one. The warrant is necessary to apprehend the thief.

Unfortunately, using the crime computer takes up valuable time in the game, and so entering data into the computer each time a clue is revealed can be counter-productive.
