CULIACAN, Mexico (AP) — Mexican security forces aborted an attempt to capture a son of imprisoned drug lord Joaquin “El Chapo” Guzman after finding themselves outgunned in a ferocious shootout with cartel henchmen that left at least eight people dead and more than 20 wounded, authorities said Friday. The gunbattle Thursday paralyzed the capital of Mexico’s Sinaloa state, Culiacan, and left the streets littered with burning vehicles. Residents took cover indoors as automatic gunfire raged outside. It was the third bloody and terrifying shootout in less than a week between security forces and cartel henchmen, raising questions about whether President Andres Manuel Lopez Obrador’s policy of avoiding the use of force and focusing on social ills is working.
