Netflix viewers say they've been left "broken" by a new documentary looking at the tragic story behind the evil murder of a mum and her young children.
American Murder: The Family Next Door tells the true story of Chris Watts, a husband and father who murdered his pregnant wife and their two daughters, who were aged just three and four years old.
The one-off programme was released on the streaming service this week, with the synopsis reading: "Using raw, firsthand footage, this documentary examines the disappearance of Shanann Watts and her children, and the terrible events that followed."
Netflix said on social media: "When Shanann Watts and her kids went missing, all eyes turned to her husband Chris.
"American Murder: The Family Next Door brings this shocking crime to life through the text messages Shanann sent before she was murdered."
A trailer shows the documentary follow the timeline from when Chris and Shanann first met, to how his story unravelled from concerned family man to twisted killer.
It includes bodycam footage from the police's initial visit to the family home after concerns were raised about the whereabouts of his family and video of Watts undertaking a voluntary polygraph test as police began to pick his lies apart.
The harrowing story has left viewers angry, terrified and in tears as they struggled to come to terms with the actions of an "abhorrent monster".
One wrote on Twitter : "Takes a lot to bring me to tears. But the last 15mins of this has broken me. I actually shed a few tears and not an emotional guy, but this got me.."
A second said: "I'm sick to my stomach over this Netflix documentary 'American Murder: The Family Next Door."
A third commented: "Gotta be one of the hardest things I've ever watched."
Someone else added: "American Murder on Netflix made my heart wrench."
