A federal appeals court on Thursday affirmed a decision to overturn the murder conviction of Brendan Dassey, a Wisconsin man serving a life sentence whose case was chronicled in the popular Netflix television documentary "Making a Murderer."

A three-judge panel of the Seventh Circuit Court of Appeals in Chicago ruled 2-1 to uphold a federal judge's ruling last year that overturned Dassey's conviction for a 2005 murder.

Magistrate Judge William Duffin had ruled in August that the conviction was based on a coerced confession that Dassey, now 27, gave as a 16-year-old with a learning disability. Duffin ordered Dassey freed in November, but his release was halted while Wisconsin authorities appealed the decision.
