The Netflix show Making A Murderer came out in 2015, documenting the story of Brendan Dassey and his uncle Steven Avery who were convicted for killing photographer Teresa Halbach.
Dassey has submitted an appeal to have his case reviewed but the US Supreme Court just announced it won't be hearing the appeal, meaning Dassey's original life sentence stands.
This isn't the first time Dassey's case has been up for review. In a whirlwind story, a judge ruled that Dassey, who was 16 at the time, was coerced into confessing and overturned the conviction. It looked like he was going to be set free until the Department of Justice appealed the ruling.
Because of the appeal, in 2017 a court decided whether or not Dassey was in fact coerced into confessing to the murders. In the end, the ruling was that he wasn't coerced. Now the Supreme Court has denied the appeal meaning Dassey will remain in jail for life.
The trial process for Dassey's uncle, Steven Avery was also long and has been reviewed but his convictions also have been upheld and both continue to serve prison sentences.
Season 1 of Making A Murderer doesn't capture the recent trials of the convicted killers but rather is filmed over a ten year period showing what happened surrounding the case and the investigation.
The popularity of the show has inspired fans to speak out and garner support to free both Dassey and Avery as many people believe the two are innocent.
Netflix has confirmed there will be a second season of the show but has not announced when it will come out or what it will cover.
