Mom pleads insanity after killing her six-year-old daughter with scissors because she spoke in an 'evil voice'

A mom charged with killing her daughter in a brutal scissor attack has pleaded not guilty on grounds of insanity.

Danielle Yvonne Slaughter, 27, claims she heard the 6-year-old speak and laugh in what she later told police was an 'evil voice'.

Slaughter spoke clearly while answering the judge's questions and entering her plea during a brief arraignment in Clark County District Court on Thursday.
