This show was so disappointing and pissed me off. Apart from it dragging on and being quite boring, the main thing that pissed me and my partner off was that in every single case there was some 'revelating' clue or fact that they never brought up again or explained. [Spoilers] Why bring up the blood and bleach and changed carpets and axe etc. in the first case and make it seem like such a murder case, when the lady was fine and somewhere else? They gave us no explanation whatsoever, horrible loose end. And what about the abuse allegations in the 2nd case? The bloodied pants and weird phone call in the 3rd one? Or the strange male picking up Sierra's phone and lying that he bought it? None of these were ever explained yet played quite a big role in each case.
I find it so stupid that they find the people and then decide that that's closure enough and never follow up.
Also some of the steps the investigators took were shockingly lame, one of the many examples being them not tracking Sierra's phone until the grandad had called it several days later. I know it was based off of real cases but it infuriated me anyway.
This show had potential and I was let down in every way
