It sounds like the family is in denial, not willing to admit one of their own could do such a thing. It mentions there being bite marks on her chest and thigh, I would think with as much evidence they won't have a problem proving who did it. These types of injuries don't happen from a fan falling on you!
It also sounds like neighbors know of problems with the family and there being issues with violence, the police were called earlier this month but no report filed. Also her 7 year old brother was there so he was probably a witness to some of what went on. Poor thing. I have a feeling there's a lot more to this story that can come out as far as the dynamics of the family.
