Wisconsin detainee "reportedly" confessed to killing "murderer"

A convicted murderer in Wisconsin reportedly confessed to killing Teresa Halbach, the photographer whose death in 2005 sparked renewed interest with the release of Netflix's "Making a Murderer" docuseries.

Halbach was killed on Halloween night after visiting the property of Steven Avery, who, along with his nephew, Brendan Dassey, was convicted of the murder. Both said that they are innocent.

A second documentary on the case, "Conviction of a Murderer", is currently being developed by director Shawn Rech.

In a recent interview with Newsweek, Rech said his team was filming the series. The alleged "confession" would have been entrusted to a "known Wisconsin murderer". Rech did not name the inmate and did not reveal the contents of the confessions.

"We have not confirmed the legitimacy of the confession, but given that it was given by a well-known Wisconsin murderer, we feel responsible for providing all the possible evidence to the forces of the world." Order and legal teams, "he said.

"After 20 months of production, we have discovered an unfathomable amount of information and evidence that leads us to the truth – our investigation does not stop there," he said.

The Manitowoc County Sheriff's Office did not immediately resubmit NBC News' comment request.

Avery's lawyer, Kathleen Zellner, said in a tweet Monday that her office received the manuscript confession but "it is worthless unless it is corroborated." Laura Nirider, a Dassey lawyer, tweeted that they are aware of the alleged confession and did not offer any other comments on it.

Avery and Dassey were both sentenced to life imprisonment in 2007 for the murder of Halbach. Dassey was 16 when he told investigators that he had helped his uncle rape and murder the photographer and then get rid of his body.

There was no material evidence linking Dassey to the crime, but he had been found guilty of statements he had made to two investigators, which, according to some, were obtained improperly. The lower courts found that Dassey's confessions, which had been made in the absence of a lawyer or his mother, were unintentional, but in June 2018, the 7th Circuit Court of Appeals American in Chicago confirmed the conviction. Avery continues the appeal process.

The two said they had been charged with the murder by police officers who were angry at Avery for suing the county for his wrongful conviction for sexual assault. Avery spent 18 years in prison for this case before DNA proved that he did not commit the attack.
