But seriously, maybe a cop was involved in the murder. We get those kinds of stories here. Maybe they wanted to cover the story up, but when FBI took step in it and when it became such a popular coverage in the media, now they don't know what to do.
When I heard the first time that she was hit heavily in the head, I don't know why but I said maybe a cop did that? Maybe it's because when I watch them beating the university students to hell with so much hatred, I do not understand where that deep of a hatred stems from.
If a cop was involved, there would be either much less evidence to follow or stronger to frame a druggie. But that happens in the movies.
