Ceci Flores, one of Mexico's best-known search activists, has taken an extraordinary and deeply painful step. In a public appeal, the founder of Madres Buscadoras de Sonora asked Joaquín "El Chapo" Guzmán to help families locate people allegedly disappeared by the Sinaloa Cartel, including her son Alejandro Guadalupe Islas Flores.
Her message came just days after Guzmán sent his own handwritten letter to a U.S. judge asking for fair treatment while serving a life sentence at the supermax prison in Florence, Colorado.
