incredible story. I really like the way this show is put together. Keeps you guessing! "No Mercy" is my favourite of this series

Excellent Series, slightly over dramatic Narrator but it's definitely one of the better US crime shows.

Heartbreaking episode with no resolution. The killer only served 16 years in prison!

I think it's important to trust that something inside, that says, no; don't trust that person, don't accept that ride, that seeming act of kindness, because it just feels off. I've had this since early childhood, and when I watch a case like this one, I wonder why all children are not born with it, or maybe they are, and convince themselves to trust, when they shouldn't. This case shook me, as it did the detectives.

This ep., as all of them are sad, and this one shows how important DNA samples became in the early part of this century, and how past crimes are solved, using smaller amounts of it.

This episode was kinda slow drawn out.although I do respect the victims, families etc..I believe some cases are just to petty and unnecessary to even mention. These criminals here are just losers for no reason.

I can't imagine myself living with someone like that and not having any idea whatsoever about these types of feelings and urges. Good for the victims to have people like the officers to care enough about them.

Smdh ...I'm on the fence with this one. The prosecution team have suspicious minds anyway but I can't say I blame them for this one. That dude is a devil in the flesh. Thank goodness on everything I believe in for The Innocence Project.

The guy in the first must be dead in regret paying for his own murder, 2 nd is one of those messed up ones where you dont know if a police officer is dangerous or helpful. Betrayal can be just as bad as murder.

Such a great show. I like these cuz they show how dedicated the authorities are to solving murders of our loved ones. Takes patience skills and more to be able to do this. Plus I like to see justice being served. Another good true crime series.

First story was just crazy. So senseless. The second really surprised me. I couldn't believe the outcome. So messed up.
