Carlito is Isabela's brother, he is behind the out break in Willmette and is from Santa Cabeza, where the zombie out break originated from. His hometown was destroyed by the U.S.A. in order to cover up what they created, which was a wasp that spreads the virus. His plan was to make an outbreak so big that the U.S.A. couldn't cover it up and show what they did to his hometown. He planned to also blow up the mall to spread the parasite even further. The last of his plan was that he may have given the virus to 50 children and sent them all around the U.S.A. to spread the virus even more, and with Dead Rising 2 taking place in Las Vegas it's most likely true.
