Mother, 34, kills her two children, then kills herself

I saw on the local news this morning that a 34-year old mom killed her two kids, ages 5 and 9, then hung herself from a fan in a bedroom with an electrical chord.

What possesses a parent to kill their children?  In this case, it’s not postpartum depression  The kids are too old.  Obviously the mom wasn’t ‘well’, but how can a parent, especially a mom, look at her kids and kill them?  There is no way I could harm my kids, much less kill them.  Sure, maybe there were times I yelled at them when I shouldn’t have.  I know I wasn’t the best mom in the world all the time and some psychologist somewhere will probably say I damaged my kids in some way, shape or form, but I love my kids.  I would die to protect my kids.

What are your thoughts?  What is with the latest trend of moms killing their kids?  Sorry for the morbid thought but I actually started a fantasy novel a while back with this as a plot line, but couldn’t finish it because I couldn’t wrap my head around the mom actually killing her kid.  What would possess a parent to do something so horrific?

I would love you hear  your comments.
