You need a very cunning and ruthless brain to be a gangster. The No. 9 gangster in this list, Paul Lir Alexander aka El Parito Loco is certainly one crafty person. He amassed his millions by hoodwinking the police and using the Feds to eliminate fellow gangsters. Finally, the law caught up with him, sentenced him to 12 years in prison, and thereafter deported him to his home country, Brazil. The Brazilian police sentenced him for 42 years but he managed to give them the slip. He is still at large but is supposedly very active on Facebook.
