Sarah Shahi portrayed Constance Welch, The Woman in White who, after discovering her husband's infidelity took the lives of her two children by drowning them in a bathtub at home and soon after, took her own by jumping off a bridge into a river.
Her ghost was known to haunt the Centennial Highway, hitchhiking unknowing motorists, mostly men, and killing those whom she deemed unfaithful.
She constantly weeps, hence her name "La Llorona." Mexican parents often use this story to prevent their children from wandering out at night.
In some versions of this tale, La Llorona will kidnap wandering children who resemble her missing children.
La Llorona briefly appears in the 1973 Mexican film Leyendas macabras de la colonia.
