All 12 judges on the federal appeals court in Chicago were hearing arguments this (Tuesday) morning on whether Brendan Dassey should go free. After hearing 60 minutes of arguments, the Seventh Circuit Court could take months to decide whether a reversal of Dassey’s conviction should stand for the brutal killing of Teresa Halbach in 2005 in Manitowoc County. The state is appealing a federal magistrate’s ruling from last year that Dassey, who’s now 27, should be acquitted because sheriff’s investigators coerced him into confessing both he and his uncle Steven Avery killed Halbach — who was at the family’s auto salvage yard taking pictures of cars for Auto Trader Magazine. Both Dassey and Avery were sentenced to life in prison. Both are challenging those sentences after their verdicts came into question in the 2015 Netflix series “Making a Murderer.”
