This myth has a tendency to take aspects of an urban legend and is present throughout Hispanic culture, even reaching Spain.
According to the tradition, La Llorona is the ghost of a woman who lost her children and now cries while looking for them in the river, often causing misfortune to those who are near or hear her.
Author Ben Radford's investigation into the legend of La Llorona, published in Mysterious New Mexico, traced elements of the story back to a German folktale dating from 1486.
La Llorona appeared as the "monster of the week" in the NBC TV series Grimm in the ninth episode of Season 2 which first aired on October 2012.
Though several variations exist, the most basic story tells of a beautiful woman by the name of Maria who drowns her children in a river as a means of revenge because her husband left her for a younger woman.
After she is challenged at the gates of heaven over the whereabouts of her children, she is not permitted to enter the afterlife until she has found them.
