Netflix documentary "Making a Murderer" had made the watchers curious about the lives of Avery's. But the latest revelation might be a shocker as Steven Avery's sons went on to claim that their father is indeed innocent. 

Steven's 25-year old twins Steven Jr. and Bill had an interview with an American documentary entitled "Crime Watch Daily." The other twin thinks their father is innocent while the other says he had no idea but feels that there is a corruption involved in the case, as NME wrote.

They also said in the interview that their father's murder conviction had taken a toll on their lives. Because of the documentary, the twins feel that part of their lives have been stolen. "The first eighteen years are the most critical, where you make that father-son relationship," said one son.

Worse, one brother revealed that he thinks the military did not hire him because of the sensational case his father had been in. The other twin also said that he wanted to take his wife surname instead, but the girl refused.

Some parts of their interview are out for checking in YouTube, but the full-length will be out on Feb. 8. On the other hand, Steven's lawyer Kathleen Zellner unveiled new evidence that can turn the table in favor of her client.

"Generally, since 2007, there have been significant advances in forensic testing ... the clearest way to do this is with scientific testing," Zellner claimed in her first TV interview.

"Am I going to tell you exactly what it is? I am not. But it's been a long time. There was a lot of evidence that wasn't tested," she added. The latest piece of evidence might prove Steven's innocence of the Teresa Halbach murder case.
