MEXICO CITY—A drug cartel bomb attack that allegedly used a fake report of a mass grave to lure police into a deadly trap has had devastating collateral damage: It has led some authorities to abandon the volunteers who search for Mexico’s 110,000 missing people.
Most of the searchers are distraught mothers looking for the bodies of the thousands of victims of kidnapping gangs and drug cartels, who dump their bodies in clandestine graves.
