José Antonio Yépez Ortiz—a gang leader in Mexico known as “El Marro” or “The Sledgehammer”—has been sentenced to 60 years in prison over kidnapping, according to authorities in Guanajuato.

Yépez Ortiz was arrested on Aug. 2, 2020 following a police shootout. His gang—Santa Rosa de Lima—was known for stealing gasoline from government fuel ducts, per ABC News, and was reportedly involved in a turf battle with the Jalisco cartel. President Andrés Manuel López Obrador has previously called the arrest “important, very important,” as Yépez Ortiz has been blamed for much of the violence in Guanajuato, according to the publication.
