Belen Diaz was walking home from college one evening when a motorcycle carrying two men made a menacing U-turn.
Terrified that she was about to be robbed for the eighth time in three years, the teaching student banged on a cab window until the driver drove her home. Diaz got away safe, but there was an unrelated fatal shooting the next day outside her gated community of two-story homes on the edge of the Ecuadorian port city of Guayaquil.
