26-year-old Brendan Dassey will have been celebrating since the news that his murder conviction had been overturned, but he may not be getting out of prison after all, with the Wisconsin Department of Justice challenging the decision.
Prosecutors think Dassey should remain behind bars despite claims from Dassey's defence that there were law-breaking problems in the way in which he was questioned and treated during his interrogations.
Brad Schimel, Attorney General comments: "We believe the magistrate judge's decision that Brendan Dassey's confession was coerced by investigators, and that no reasonable court could have concluded otherwise, is wrong on the facts and wrong on the law.
"The investigators did not use constitutionally impermissible tactics.
"Two state courts carefully examined the evidence and properly concluded that Brendan Dassey's confession to sexually assaulting and murdering Teresa Halbach with his uncle, Steven Avery, was voluntary."
Dassey's lawyer and family responded in a statement: "We are disappointed in the State's decision to prolong Brendan's case by seeking an appeal.
"We look forward to continuing to defend his rights in court. Like Brendan, we remain grateful to his many supporters for their continued loyalty and strength."
