But all is not as straightforward as it seems. The narrative packs in suicide, suspected murder, teen romance, mental health struggles, tragic text messages and a landmark murder trial that set a fascinating precedent about the power of words. But what is the true story behind the drama?
On 13 July 2014, 18-year-old Conrad Roy was found dead in his truck in a car park behind a supermarket in Fairhaven, Massachusetts.
The pair bonded over their mental health struggles. Carter was isolated at school, and suffered from anxiety and an eating disorder that – during the time period of her relationship with Roy – necessitated a stay at a residential clinic. Roy himself had already made several suicide attempts.
