One of the first big murder mystery docuseries that captivated the world was Making A Murderer.
It followed the legal battle with Steven Avery, who was accused of murdering Teresa Halbach after she rocked up to his place to take some photos of a car.
He was eventually convicted and sentenced to life in prison, but the case really divided people between those who reckon he's innocent and those who think he's a cold blooded killer.
There has been a back and forth between his legal team and the state prosecutors over dodgy evidence and accusations of a cover up.
Well Avery's lawyer Kathleen Zellner has revealed that she's been accidentally sent information about evidence that could be vital to getting him out of prison.
Ms Zellner says Attorney Mark Williams called her by accident, when he was supposed to be ringing Assistant Attorney General Thomas Fallon.
He left a voicemail, according to the Mirror, saying: "Hi Tom, this is Mark Williams. I'll send you an email later today, but I don't think we should do anything or respond to her at all until tomorrow, uh, when we look into the bag - and see exactly the pelvic bones are in there or not.
"So I wouldn't respond until we look into the bag tomorrow morning and then we can talk about it before we send a response. Thanks a lot. Bye."
Steven's lawyer reckons that bone will prove that Teresa wasn't murdered by Avery and it was planted in his car lot.
She's asked the State to provide information on where that bone is but her calls have gone unanswered. This voicemail, she alleges, proves that prosecutors are trying to avoid speaking to her.
In a letter addressed to the Wisconsin Court of Appeals, Ms Zellner writes: "...as the attached transcript and CD illustrate, the State is trying to deceive undersigned counsel and this Court about the status of the pelvic bone, which was recovered in 2005 from the Manitowoc Gravel Pit."
Ms Zellner is hoping this letter will push Steven's case forward.
His lawyer, according to the Mirror, has one of the highest success rates at overturning wrongful convictions in the US, so it sounds like she knows what she's doing.
Steven has been in jail since 2007 and was sentenced to life in prison without the possibility for parole.
It'll be interesting to see whether this is the missing piece to the puzzle to get Avery another chance at freedom.
