Grove Street Families hitman Carl Johnson, also the "Underboss", attacked the territory of the Mountain Cloud Boys, one of the San Francisco Triads, which was an ally of the GSF. Johnson shot three of the Triads, starting a wave of Triad associates. The first wave was mown down, but the second wave was tougher, armed with SMGs and Assault Carbines. Johnson took cover and murdered the second wave, and since he had killed all of the Triads, he took over Calton Heights.
