I'm sure this article has already been posted since I've been gone all day but haven't seen anything about the mom being arrested, has she?

DeRyke told investigators he was home alone with Willow and her three-year-old brother Saturday night when Willow accidentally scratched him, according to court documents obtained by the station. This reportedly angered him and caused him to yell at Willow which in turn led her to run out of the house and towards a brush pile in the family's backyard.
DeRyke reportedly told police Willow began to twitch and he believed he had to end her suffering, so he grabbed a knife out of his bedroom,
slit her throat and then stabbed her in the heart approximately five times.
