Small Town Bank
As Catalina robs the bank, Carl's role is to aim the shotgun Catalina gives him at four bank employees in order to continue scaring them into keeping their arms raised. If they lower their arms (or Carl decides to pull the trigger on one of them!) then an alarm will sound, and a three-star Wanted Level will ensue. Police arrive and Carl will have to shoot his way out, then he and Catalina flee on stolen police motorcycles from the scene of the crime.
The reward for successfully completing this mission is $10,000.
