After "Making a Murderer" was aired in December 2015, the docuseries became an overnight sensation, and Avery was able to get a new powerful counsel that may help him get out of prison. Steven Avery earlier condemned his former lawyers Dean Strang and Jerry Buting for being ineffective as he continues to serve life amidst his claimed innocence.

In a handwritten, open letter of Avery, convicted over the murder of Teresa Halbach in 2005, wrote that he is blaming Strang and Buting for his guilty verdict. He believes that his former lawyers committed negligence on investigating and presenting significant evidences that could overturn the case filed against the "Making a Murderer" star.

"Good lawyers don't take it personally," Buting told Newsweek in a long interview. "We're human beings, [law] is a human endeavor and as long as it is, even the best can make mistakes."

The lawyers, who is presently in the United Kingdom on a speaking tour, A Conversation on Justice, became household names with the "Making a Murderer" docuseries. Despite Avery's move to publicize his anger to Strang and Buting, it looks like that his previous attorneys still managed to understand their former client's resentments.

Buting thinks that Avery is frustrated with the whole scenario because he is still in prison, adding that he has spent half of his entire life in the jail, serving the repercussion of something that he did not do. He defended Avery by saying that he personally believes that the latter is wrongly accused.

Strang, on the other hand, thinks that what pushed Avery to blame them is more of his frustration than his fury. He added the "Making a Murderer" star's emotion is "quite understandable."

Avery's new lawyer Kathleen Zellner has since blamed the two lawyers for their incapacity to investigate further on Halbach's mobile phone. Zellner argued that Halbach left Avery's place alive, and the victim made phone calls to someone who had a history of sexual assault during that time.

As Avery's nephew Brendan Dassey's conviction was overturned in August, Wisconsin  Attorney General Brad Schimel recently requested the Federals Appeals Court to reverse the earlier decision and confirm the "Making a Murderer" conviction. Schimel believes that Dassey's confession was voluntary and no "substantial police coercion" happened, according to FOX News.

Dassey admitted that he helped his uncle Steven rape, murder and mutilate Halbach during an interrogation in 2006. He filed an appeal to the federal court, defending his side that his rights were violated during the interview.

When "Making a Murderer" Season 2 returns, viewers can expect to see a more thrilling turn of events in the docuseries. Zellner promised to present a new suspect and evidences that will prove her client's innocence.
