The case of Steven Avery and Brendan Dassey has been followed by a lot of people ever since it was adapted into a documentary television series on Netflix. Now thatMaking a Murderer” Season 2 is soon to hit the small screens, one of the suit’s investigators revealed he still doubts and questions the result of the murder.

To recall, Steven Avery and his nephew Brendan Dassey were put into a life sentence in prison in 2007 for the killing of the photographer Theresa Halbach in Manitowoc County. In fact, when the show was first seen in 2015, a lot was angered noticing that the investigators compelled the 27-year-old convicted’s interrogation that led to their guilty verdict.

Brendan Dassey pressured by police officers to confess

“Are there parts of it that [Dassey] may not have done? I don’t know. You know, I just don’t know,” the investigator named Tom Fassbender told NBC News for a special episode of “Dateline.” Feeling quite hopeless that he can’t solve the two’s case, he only said that someone should come forward, to tell the truth finally.

“Those officers wanted that information in the worst way, and they got it in the worst way. By feeding it straight to Brendan Dassey,” an attorney at Northwestern University’s Center on the Wrongful Conviction of Youth Laura Nirider said. In fact, a federal magistrate judge reversed his conviction in August 2016 declaring that the investigators took advantage of his youth and cognitive disabilities.

Department of Justice denies investigators coerced interrogation

Brendan Dassey was just 16 years old that time and the arbitrator even added that they tricked him to confess by making a promise that he would be fine. However, the Department of Justice appealed. Thus he is still inside the prison waiting for the result.

Meanwhile, DOJ and Brendan Dassey’s lawyers presented oral arguments at the 7th U.S.
