Mothers killing babies?

I'm sure at least 98% of the world is still either mad, frustrated, or in disbelief after learning Casey Anthony's was found not guilty in the murder of her 4 year old daughter Caylee Anthony. What gets the viewers all worked up is the fact her daughter was missing for days while she was out partying! Although the law could not prove her guilty, that's does not mean she was innocent in my opinion. However it seem like ever sense that case, more children are being abused or killed by their mothers, and fathers too. Lets take Yokeia Smith of East St. Louis for example. The 25 year old mother is accused and has been charged for “the killing of her 2 youngest children” 5 year old Levada Brown and 4 year old Yokela Smith. Not only did she “kill her children” she went on a rampage and struck random pedestrians, but thankfully she surrender outside of KMOV-TV news station in the downtown area of East St. Louis. Lets all hope another guilty person(s) does not get off the hook.
