– At least seven people were killed in Acapulco yesterday in what police believe was a clash between rival drug gangs. Guns and grenades were used to attack a house in a residential part of the resort city, AP reports. Further north, suspected cartel hitmen killed the mayor of a small town outside Monterrey as he drove to his ranch. Mayor Prisciliano Rodriguez is the fourth public official assassinated in Mexico in just over a month, Reuters reports. As cartel violence continues to plague Mexico with no end in sight, mob justice is on the rise, reports NPR. In a small town in Chihuahua state where kidnapping and extortion have soared over the last two years, a mob pursued a gang that had kidnapped a teen girl, killing one and beating two others. Police took the beaten pair to a military base, where a crowd of around 1,000 broke through the gates, seized the men, and locked them in a hot vehicle where they eventually died. The town's mayor fired all 14 of the town's police officers the next day.
