5 detained in kidnapped boy’s slaying

Mexico City police said they have detained five suspects in the kidnapping and killing of a 14-year-old boy, a crime that prompted protests across the nation.

Officials said kidnappers dressed as police and set up a fake checkpoint on a busy street to snare victim Fernando Marti, revealing the complexity and sophistication of Mexico’s organized crime gangs.

City prosecutor Miguel Mancera said the suspected ringleader, Sergio Ortiz, posed as a well-heeled society type to move among the wealthy and collect information on potential victims. Mancera said Ortiz was a former agent of a now-disbanded city detective force.
