A federal judge in Milwaukee moved Friday to overturn the life sentence of Brendan Dassey, one of the subjects in the "Making a Murderer" series last year.
Dassey, 26, and his uncle Steven Avery, were prosecuted for the murder of 25-year-old freelance photographer Teresa Halbach in 2005, and two years later were convicted.
Court documents obtained by ABC News show the investigators made "false promises" to then-16-year-old Dassey, including how "investigators repeatedly claimed to already know what happened ... and assured Dassey that he had nothing to worry about." The judge ruled that in light of those lies, coupled with "Dassey's age, intellectual deficits and the absence of a supportive adult," the confession was "involuntary" and therefore invalid.
The judge's reversal of the conviction may be the result of public outrage or the availability of new information following the release of the Netflix true crime series in December. The documentary suggests the two men were wrongfully accused in Halbach's death.
