Oxygen knows true crime. The channel has aired an impressive thirty-four seasons of Snapped, one of the original shows willing to explore the core question at the heart of all crime: what drives someone to commit atrocious acts of violence?
There are no easy answers, and perhaps that’s why the genre has taken off so spectacularly in recent years. We want to know. But every crime has its own catalysts, its own series of cause and effect, that knowing often feels elusive.
Still, there are insights to be gleaned, lessons we can learn, and for many, the confirmation that we are not alone in both our fear and our desire for justice.
And Oxygen has made it easier to watch their massive library of true crime documentaries by streaming on Peacock.
If you’re looking for new true crime documentaries, here are eleven new Oxygen releases you can watch right now.
