‘Making A Murderer”s Brendan Dassey denied Supreme Court appeal

Lawyers for Dassey have vowed to continue fighting his case...

The US Supreme Court has refused an appeal bid for Brendan Dassey, the nephew featured in acclaimed crime documentary Making A Murderer.

Lawyers for Dassey, who is now 28, attempted to challenge his conviction for assisting uncle Steven Avery in the killing and mutilation of freelance photographer Teresa Halbach in Wisconsin in 2005.

Although Dassey initially confessed to the crime, his lawyers have argued that the then 16-year-old experiences¬† “significant intellectual and social limitations” and was forced to confess to a crime he didn’t commit.

Footage of Dassey’s interrogation features in Making a Murderer, with his lawyers claiming that he was repeatedly questioned four times in 48 hours.

Dassey was convicted of helping Steven Avery in the killing and mutilation of freelance photographer Teresa Halbach in Wisconsin in 2005.

“The video of Brendan’s interrogation shows a confused boy who was manipulated by experienced police officers into accepting their story of how the murder of Teresa Halbach happened,” his lawyers said.

Fresh hopes for Dassey’s release were raised in 2016 after a¬† federal magistrate judge found that his initial confession had been coerced.

However, subsequent re-hearings concluded that he had spoken to police with his mother’s permission and provided investigators with incriminating responses to open ended questions.

Responding to the latest verdict, Wisconsin attorney general Brad Schimel said: “We hope the family and friends of Ms Halbach can find comfort in knowing this ordeal has finally come to a close.”

Lawyers for Dassey have vowed to keep fighting his case, claiming that the teenager faced lies from investigators. They also claim that “many options” are still available for the 28-year-old.
