Even though multi-level marketing feels like a cult, it’s usually nothing more than a petty pyramid scheme.

6. Lorena

Netflix crime documentaries - Lorena

During the 90s it became nearly impossible to escape gossip news. With networks broadcasting longer, the need for more topics grew. And true crime became a ratings sensation.

Oftentimes due to networks sensationalizing events, we feel a disconnect from the situation. Instead of tragedies, they become our nightly entertainment. Of course if anyone is guilty of letting their morbid curiosity get the best of them, it has to be true crime fans.

But some cases become bigger than the genre itself, as seen with Lorena Bobbitt.

In the 90s Lorena Bobbitt threw her husband’s severed penis into a field. And even today it’s seen as a running gag. However, when you take a look at the big picture, it’s a tragic tale.

Instead of making crude jokes about the case, Jordan Peele’s Lorena challenges the viewer to see the case from a new perspective. Because the Bobbitt household wasn’t a happy one. And Jordan Peele’s 2019 true crime documentary serves to reexamine the events driving Lorena’s actions.

But it didn’t stop there. Berkowitz then shares that he gets orders to kill from his neighbor’s dog.

Even though prosecutors have a confession, questions about the murders remain. Did Berkowitz act alone? Or did he mean it when he said that there are other Sons out there?

The Sons of Sam is a true crime documentary that sets out to document the personal investigation of Maury Terry. And Terry’s evidence points to more than one assailant.

There’s big money in antiquities and historical documents. And where there’s heavy cash flow, it’s safe to say there’s crime. Which sets the stage for Mark Hoffman, a master forger and renounced Mormon, to make money off of the LDS Church.

But eventually Hoffman’s prolific forgery enterprise blows up in his face – literally.

11. Unsolved Mysteries

Best true crime shows - Unsolved Mysteries

One of the biggest names in true crime documentaries is Unsolved Mysteries. And Unsolved Mysteries has been casting new light on cold cases since the 80s. Even helping to solve or bring new evidence forward with cases the series covers.

After the docuseries went off the air for a decade, it came back streaming on Netflix. Between the show’s original popularity, and the current demand for true crime documentaries, Unsolved Mysteries is getting a second season.

For the Netflix series, the creators use a strict crime documentary format. Unlike the original show that would shift between chilling tales of paranormal events, and unsolved cases.

You can catch up on the Unsolved Mysteries reboot streaming on Netflix before the next season airs in 2023. Or stream older episodes on Hulu.


12. Forensic Files

Netflix mystery series - Forensic Files Collection

If you’re looking for a true crime documentary series that’s perfect for casual viewing, then check out Forensic Files. Additionally, you’ll get 14 years of in depth, yet episodic, retellings of criminal investigations and the science behind the scenes.

When first on the air, Forensic Files goes by the title Medical Detectives–which ultimately fails to match the direction of the show. Originally, the show focuses more on medicine, infectious diseases, and accidents. But the ratings for the true crime episodes steal the show. Ergo the name change.

Instead the show focuses on the forensic sciences behind the cases. And unlike many true crime docuseries, Forensic Files covers both big and small cases. As long as they can highlight the investigation’s use of forensics.

And since it’s episodic, you can jump around. Or just binge the entire collection on Netflix, and Hulu.


13. I Am a Killer

Serial killer documentaries Netflix - I Am a Killer

While so many true crime documentaries choose to simply discuss the perpetrators, some take it even further.

With the true crime docuseries I Am a Killer, each episode features a new death row inmate. And each inmate has a chance to tell their version of events.

So, you don’t learn about their crimes solely from the investigative point of view–or just from the point of view of the victim’s loved ones. Instead, you hear it from the very people that are locked up for those crimes.

Find out exactly what drove these people to kill. And hear them out as they discuss the crimes they’re currently awaiting execution for.

If you enjoy getting into the mind of murderers, and convicts, then I Am a Killer is a must-watch show.

Following his release, and as of May 2006, Avery is the only exoneree from Project Innocence to be charged with a violent crime.

But there are some issues with Avery’s case. However, with the popularity of Making a Murderer, new information is coming to light. And Avery’s legal team is still working hard to discover the truth.
