I have been thinking about this for a long time and I am not sure how to fit this in with everything else.
Was the uncle directly involved? Was Saras death a result of disobeying the uncle, or worse, fighting some (sexual?) abuse by the uncle and he ended up killing her without that being directly connected to the previous abuse she suffered (mostly) at the hands of her immediate family? Meaning the previous abuse seen on her was more of a "symptom" of things being wrong at the family than directly connected to whatever incident caused her death?
Was the uncle there, but not the killer? How did he relate to their daily life? Was he, for example, teaching Sara something? Was he actually living there? Was he just visiting for some unrelated reason at that time?
Was the uncle not involved with the death at all? Did the uncle just run over there after it had all happened and helped the family out and fled to avoid questioning and being accused of being an accessory to them running away? There was the talk of 2 cars leaving and I don't know how these 2 cars relate to anything.
Were there even more people involved, who did not flee with them? (but could have been in one of the 2 cars initially)
So many questions, so little answers. MOO.
