Netflix has released a new true-crime documentary exploring the story of Chris Watts, a man who was found guilty of killing his pregnant wife and two children.
The feature-length documentary, titled American Murder: The Family Next Door, lands on the streaming site nearly two years after Watts was sentenced to serve five life terms in prison for the murders of Shanann Watts, her unborn child and her daughters.
Netflix's synopsis for the programme reads: “Using raw, firsthand footage, this documentary examines the disappearance of Shanann Watts and her children, and the terrible events that followed.”
So, here's what you need to know about the case:
What happened to Shanann Watts and her daughters?
The case involving Chris and Shannan Watts began with the latter, who was 15 weeks pregnant, being reported missing by a friend on August 13.
Following an initial police search of the couple's house, Ms Watts and the pair's daughters - Bella, 4, and Celeste, 3 - were officially declared missing a day later.
Mr Watts then went on a publicity spree, appealing publicly in a series of television interviews for help in finding his missing family.
But the following day, on August 15, he was arrested for the murder of his wife after failing a polygraph test and confessing to killing her.
But he did not confess to killing his daughters, saying instead that Ms Watts was responsible for their deaths and that was what prompted him to murder her.
He later confessed to murdering the two girls, however, and told detectives that he had been having an affair.
He had murdered his wife at home before driving her body and his children, who were still alive at the time, to an oil field. There, he buried his wife in a shallow grave and smothered his children before dumping the girls in separate oil tanks.
What sentence did Chris Watts receive and where is he now?
Mr Watts was spared the death penalty at his sentencing in November 2018 when he pleaded guilty to all nine charges in the case, including three counts of first-degree murder; two counts of first-degree murder of a person younger than 12 while being in a position of trust; one count of unlawful termination of a pregnancy; and three counts of tampering with a deceased human body.
He is currently being held at Dodge Correctional Institution, a maximum-security prison, in Waupun, Wisconsin.
