As if Mexico’s drug wars weren’t perverse enough already: On Thursday, Mexican authorities arrested Santiago Meza Lopez, otherwise known as “El Pozolero” or “The Stew Maker.” Why the nickname? He used the grisly tools of acid and human remains—always male, as he refused to melt women—to “disappear” the enemies of Teodoro Garcia Semental, a notorious drug baron. Lopez was paid $600 a week and he claims to have “disappeared” 300 people. Relatives of 100 missing people want to show Lopez photos of their loved ones in hopes he will remember their faces. Lopez apologized to the relatives of his victims.
