Social Welfare Adjunct Professor Jorja Leap spoke with BBC World Service’s Spanish-language news outlet about the Fulton clique of the MS-13 street gang. A federal indictment of 22 of the gang’s members detailed brutal acts across Los Angeles, according to BBC Mundo. Federal officials said 19 of those indicted are undocumented immigrants from Central America who arrived in the past three or four years. The Fulton clique actively recruits young people, who often behave impulsively and unpredictably, Leap said. Youths who have experienced poverty, poor education, trauma and mental illness are particularly susceptible to gang overtures, she said. The indictments came as MS-13’s influence in the region has waned. Leap said 1,200 homicides were recorded during MS-13’s boom, but last year the number had dropped to 300.
