"La Llorona" Hits Me Between The Eyes!

There are some stories that are so visceral and intense that they grab ahold of your mind and won't let go.  I heard one of these stories from an episode of "Grimm", titled "La Llorona."  The show blew my mind, and is going to be the only modern television show that I am going to follow because most TV is junk.  It also introduced me to a Spanish myth that I want to include in my book series.  In it, a woman named Maria drowns her children in a rage after her husband ditches her, only to regret it later and drown herself as well.  She then haunts rivers and lakes as a malevolent ghost named "La Llorona", which means, "the Weeping Woman."  Late at night, she captures and drowns children.  After doing some digging, I was pleased to find out that "Grimm" was pretty faithful to the myth.  The only real difference is that, in the show, she had three children instead of two, which was a change made for plot-related reasons.  At any rate, the story is still haunting me, which is why I am going to include the myth in my own book series.  Even though my series is biblically-based, I am a huge lover of mythology and include those tales as well.  This one will be used for the most dangerous human character whom I have ever created.  After encountering her, I want my readers to feel the same chills which I was given by the "La Llorona" myth.  Now, obviously, I am going to take some artistic liberty with the tale so that it will fit better into my world.  At the same time, the core, creepy spirit of it will stay the same, so that it will still hit my readers between the eyes!
