Fla. mom says she killed children for being 'mouthy,' police allege

A Tampa woman is accused of killing her son on the way to soccer practice, and then coming home to murder her daughter, who was working on a computer. The alleged motive?

Julie Schenecker left a note detailing her plans to kill her disrespectful children and then herself, saying "they talked back and were mouthy and that she was going to take care of it," McElroy said. She provided the same motive to police who interviewed her.
