Kathleen Zellner, attorney for convicted murderer, Steven Avery, revealed that she was sent a handwritten confession letter from a man admitting to killing Theresa Halbach.
The man, named Joseph W. Evans Jr., is currently an inmate at a facility in Biscobo, Wisconsin, but claims he was responsible for killing and burning Halbach's remains, as well as destroying her personal belongings.
Zellner revealed that, "We received the handwritten confession on Saturday," but admitted, "It is worthless unless it is corroborated."
The letter was sent after Zellner made a public announcement that a reward of $100,000 was being offered for any information leading to the rightful killer of Halbach.
Evans, who is already in prison for murder, wants the reward and is willing to offer up his entire story for a little cash incentive.
He asked Zellner to put $2,000 on his prison books as a show of good faith before he reveals the whole story.
In the letter, revealed by Zellner, Evans writes that he accidentally struck Halbach with his vehicle outside the Avery property on October 31, 2005 and then disposed of her remains to cover up the accident.
He also claims to have shot her multiple times and then burned her remains in a fire that he tended. Evans also claims he burned her cell phone, computer and other evidence that identified the woman.
The Wisconsin Department of Justice verified that a letter was sent, and claims that the "confession" from Evans contradicts statements he's previously made:
“The Wisconsin Department of Justice has received the new information related to the case. DOJ takes all credible reports seriously, but it’s important to note that this new information directly contradicts information previously provided by the same individual."
Fans are also skeptical of the letter, as a fiery debate has ignited online to the legitimacy of Evans' claims.
"It seems off," one fan wrote, adding that, "Like he was put up to writing it and taking the fall for the misdeeds of law enforcement. He hits her by accident and turns it into a huge set up by shooting her and taking a band-aid and tissues? Why not just leave? No one seemed to know he was there."
Other fans don't trust the letter, but still believe Avery, and his nephew Brendan Dassey, are innocent: "I'm sorry but it seems like someone's trying to get $ I really don't believe this, but I do believe Steven and Brendan were set up."
Steven Avery is currently appealing his 2007 conviction of 1st Degree Intentional Homicide.
In August, a judge denied the star's request for a new trial based on alleged mishandling of the evidence. His case is currently being heard in appeals.
Dassey is also serving a life sentence for the murder of Theresa Halbach, and had filed an appeal claiming his confession was coerced by aggressive investigators. His appeal was denied and he continues to serve his sentence.
The Halbach murder has garnered worldwide attention after being showcased for 2 seasons on Netflix's "Making A Murderer."
