A massacre in the San Pedro Sula suburb of Chamelecón left 27 dead and 29 injured. The murderers left behind a message, claiming to come from the Cinchoneros, railing against Maduro, Lobo, Álvarez and the death penalty. The Cinchoneros are believed to be defunct, however. The attackers promised another massacre before the new year. However one suspect was detained very shortly afterwards in another part of San Pedro Sula, and further arrests were later made. Local police said that the gunmen were members of the street gang Mara Salvatrucha (MS-13), and the supposed mastermind of the attack, Ebner Anibal Rivera-Paz, was later arrested in Falfurrias,Texas.
