How 'La Catrina' became a symbol for Mexico's Day of the Dead

Mexicans are celebrating "Dia de Muertos," an annual holiday where families honor deceased ancestors. One popular character always shows up: La Catrina, a fancy skeleton lady wearing an elegant dress and a flowered hat. Last year, The World's Tibisay Zea went to a big parade in Mexico City, to get the story behind La Catrina's starring role in the seasonal festivities.
