The attorney representing an inmate featured in the "Making a Murderer'' series is vowing to keep fighting for him after the U.S. Supreme Court refused to take his case.
Brendan Dassey's attorneys contend investigators coerced him into falsely confessing that he helped his uncle, Steven Avery, rape and kill photographer Teresa Halbach in 2005.
Dassey was 16 at the time.
He was sentenced to life in 2007.
A federal judge overturned his conviction in 2016 but a federal appellate court upheld it.
His attorney, Laura Nirider, said in a statement that investigators lied to Dassey and fed him facts that fit their theory of the crime, confusing him.
She could still get Dassey a new trial but she'd have to convince a judge that they have new evidence that warrants one.
His lawyers wanted his confession thrown out and for the court to order a new trial on the basis that he is borderline intellectually disabled and was pressured into a false confession.
