Murdered teen was just days from fleeing East Boston back to Guatemala

The Globe talks to relatives of Cristofer Perez de la Cruz, murdered in East Boston earlier this month, had bought a ticket to return to his native Guatemala, rather than get caught in the violence between MS-13 and the rival 18th Street gang.

Friday's sweep of alleged MS-13 members is beginning to provide the background for numerous murders and other acts of violence in East Boston and neighboring cities in recent years.

Kevin Cullen reports that Rogelio Alvarado, an MS-13 member, opened fire on a rival gang member on a Blue Line train at Maverick - hitting that guy and a bystander.

The Herald talks to City Councilor Annissa Essaibi-George about MS-13 recruiting at East Boston High School, where she taught until she was sworn in as a councilor this month, as well as City Councilor Sal LaMattina, who attended a community meeting on violence the night before the arrests.
