11 True Crime Docs On Netflix UK That'll Seriously Test Your Detective Skills

'The Alcàsser Murders' / Netflix UK

Getting into a true crime documentary marathon is just that. A marathon, not a sprint. It requires time, dedication, and a lot of snacks. Right now, more and more people are becoming interested in the genre, and streaming platforms are absolutely delivering the goods. So, with that in mind, I've rounded up the best true crime documentaries available on Netflix UK to save you scrolling and ensure you have maximum viewing time to make it to the finishing line of your marathon. God speed.

The criminal world has, of course, always been hugely fascinating to members of the public. That fascination with those who commit hideous crimes, who live the the glamorous lives of mobsters, or claim to have been falsely accused of something they didn't do, has resulted in a huge uptick of true crime documentaries, in which journalists and other famous faces take us through each story, moment by moment, and allow us to begin a little investigation of our own.

Netflix is one of the best producers of criminal-minded content. Not only do they produce movies and series, but they chuck the whole season up at once, leaving you praying for a rainy day or even a major hangover so you have an excuse to fill up your criminal cup. Well, that cup is about to overflow guys. Get drinking.

'Evil Genius' — 2018

A fake robbery. A pizza delivery man. A bomb.

I can't describe this story because you just have to see it for yourself and, also, it's just too wild to explain. Gripping from start to finish.

'The Staircase' — 2018

The Staircase is a multi-part series documenting the case surrounding the death of Kathleen Peterson. It is one of the most compelling "did he, didn't he?" type of productions you will ever see. I mean, seriously — I have had actual arguments with people over this.

One of those ones you will be desperate to discuss (argue about) with friends.

'Amanda Knox' — 2016

When British student Meredith Kercher was found murdered in her flat, her flatmate Amanda Knox instantly fell under suspicion. Trial by public opinion ensued with a media obsession over Knox, her boyfriend, and their personal life.

'Dirty John: The Dirty Truth' — 2019

This true story was first told on the podcast Dirty John and is honestly too dramatic to even believe. It's the story of conman John Meehan and how he duped many women into funding his lifestyle by manipulating them into loving and trusting him. Which cost them not only financially, but emotionally too. This documentary goes further than the podcast and focuses on more of his victims as well as the steps that led to his demise.

'Out Of Thin Air' — 2017

This documentary is all about the case concerning the disappearances of Guðmundur Einarsson and Geirfinnur Einarsson in 1974 in Iceland. After they disappeared, six people were charged with their murders having confessed to the killing. Cut and dry case, right? Well, not quite. The confessions were allegedly taken while the six interviewees were under extreme duress and are now believed by many to have been false. Meaning that six innocent people might have been charged with murders they didn't commit.

Before this terrible video went viral, however, Magnotta had already created and shared videos of himself killing kittens. Knowing the long-held belief that actions like this often escalate to even worse behaviours, web sleuths bandied together to try and find him.
