Homero Gómez was apparently murdered on January 13th

EVERY YEAR, in early autumn when the chill begins, clouds of bright orange Monarch butterflies rise from the flowers on which they have been feasting in eastern Canada, and head south. They overfly the American Midwest and Texas until, below them, lie the scattered stone houses and corrugated shacks of El Rosario and Ocampo, in the western Mexican state of Michoacán. There, after an astonishing flight of around 4,500 kilometres, they descend to mountain forests of oyamel pine, their favourite tree; and on these they hang to rest and overwinter, so many thousands of them that the branches are weighed down and the trees seem draped with orange leaves. About half of all Monarchs come to this exact, remote place every year, and always from around the same day: November 2nd, Día de Muertos, the day of the dead.
