Brendan Dassey, the nephew of Steven Avery, has been ordered released from prison by a federal judge. His murder conviction was overturned. Dassey did say that he assisted his uncles in the murders, but attorneys felt like the confession had been coerced by police.
They also argued that his constitutional rights had been violated. Dassey was 16-years-old at the time the murders took place. His uncle Steven Avery is currently serving a life sentence in the murder of Halbach.
