Making a Murderer’s Brendan Dassey had already given away most of his prison property to other inmates when he received the shocking news that he has to stay in prison.

All he had left was a television which he had held on to because he wanted to watch the twists and turns of his case, his uncle Earl Avery told DailyMail.com exclusively.

‘He’s given away his food, everything,’ said Avery.

Dassey, 27, will have to stay behind bars while state attorneys appeal a decision to overturn his conviction, a panel of federal appellate judges ruled on Thursday.

Doubt: Brendan Dassey (pictured in Manitowoc County Courthouse in 2010) was ordered released on Monday but he has been told he will now have to stay in jail for the time being

Dassey was due to be released by 8 pm. Friday a judge ruled earlier this week, but on Thursday a three-judge panel from the 7th U.S. Circuit Court of Appeals in Chicago reversed its decision around noon on Thursday.

‘It’s terrible,’ his grandmother Doris Avery told DailyMail.com. ‘That’s all I have to say.’

Dassey and his uncle Steven Avery were both sentenced to life in prison in 2007 for the rape and murder of photographer Teresa Halback two years earlier. Their case got international attention when it was featured on Netflix’s 10-part documentary Making a Murderer.

‘He’s got nothing in prison now,’ said Earl Avery, 46. ‘He gave away three-quarters of his stuff.

‘I don’t understand how these judges can have overturned the decision to release him,’ he added at the family’s auto junkyard in Two Rivers, Wisconsin.

‘’It’s just so disappointing. We had hoped to have him home for Thanksgiving, but now that’s not going to happen.

‘He was going to live with his mother, everything was set up and now he has been given this news. We are all devastated.’

Dassey, who has been described as a perfect prisoner even earned his high school diplomacy while inside Correctional Institution in Portage, Wisconsin, a two and a half hour drive from his home.

Earl Avery said he worried about the effect the news of the delay may have on his nephew. ‘He has done really well while he was locked up and this could affect him badly,’ he said.

In August, a federal judge overturned Dassey's conviction, ruling investigators coerced him into confessing. Wisconsin's Department of Justice appealed that decision to the 7th Circuit.

The judge on Wednesday ordered Dassey released from prison by 8 p.m. on Friday. The DOJ filed an emergency motion with the 7th Circuit hours later seeking to block the release.

Speaking after the latest ruling, attorneys for Dassey said they were 'disappointed more than words can say'.

Avery was sentenced to life without parole for killing 25-year-old Halbach on October 31, 2005, alongside his nephew Dassey, then 16, who at the time had a mental age of nine, and was interrogated by police without an adult present.

At the time of his arrest, Avery was suing Manitowoc County for $36 million over being wrongfully imprisoned after facing 18 years for sexually assaulting Penny Beersten.

Dassey had his original conviction quashed by Judge Duffin in August, who said investigators tricked him into a confession, but that ruling is being appealed by the State.

According to family confidant and prison campaigner Shaun Attwood, supporters have been thinking it's a 'foregone conclusion' that Avery will be set free because his lawyer Kathleen Zellner is demanding the court uses new forensic DNA testing methods, which she says will prove that Avery's blood had been planted in Halbach's Toyota RAV4 car - and is actually older than the vehicle itself.

High profile Chicago-lawyer Zellner has headed up Avery's legal team since Making A Murderer became a global Netflix sensation.

She specializes in wrongful convictions and, so far, has a 100 per cent success record, exonerating 18 innocent people.

She says that new evidence will not only clear Avery, but promises to reveal the identity of the real killer.

Yet, 47-year-old Attwood says that Wisconsin state prosecutors - led by Attorney General Brad Schimel - will do anything to keep Avery locked up and are armed with tens of millions to fight a 'dirty' legal battle.

The news of of Dassey's release order had been greeted with delight by his supporters, including his aunt Carla Chase, who wrote on Facebook: 'I want to thank everyone personally for all the continued support & fighting with us for months…

'The support that everyone has given has been awesome & we greatly appreciate everything. We consider you our extended family & we will try to keep you updated with the latest news coming in.'

His mother, Barb Tadych, admitted to the Daily Mail that he is a 'little bit of scared of going into the outside world' and the family will be 'starting from zero'.
