Lawyers acting for Steven Avery are to hit a 'gold mine' of potential evidence as 4,000 pages of secret emails are set to be released on his case.

Information contained within the documents could shed new light from behind the scenes offering up nuggets of information about the Making a Murderer Netflix series that have so far have been kept in secret.

The state of Wisconsin has agreed to release the information as Chicago-based lawyer Kathleen Zellner gets set to take her appeal case to court in Manitowoc County in the coming weeks.

Avery's existing bail application has been delayed after prosecutors once again asked for an extension meaning the case will not see movement until March 11.

The emails to be released in the coming weeks come after a request by US investigative reporter Keegan Kyle who has been battling with the prison service to get access to information on the Avery case.

Now campaigner Shaun Attwood says the case could be blown wide open thanks to the close ties the prison service has with the Sheriff's office.

He said: "With so many prison staff being related to key people in the Sheriff's department, that were part of the Avery investigation, all kinds of inside information could be revealed in these emails.

"Form internal communications released by the prison we already know that there are conflicts of interest so there could be explosive information in there that could blow the lid off this case.

"It's an exciting development."

Now a prison spokesman has confirmed they are "committed" to providing information.

While some of the information will be redacted or held back - the vast majority of information will be released allowing the public to pore over the documents as thousands of campaigners continue to back the campaign for a retrial.

A Wisconsin Prison Spokesman said: "Once the information has been appropriately redacted, we would be happy to provide the information either in hard copy, for which there is a per-page fee, or in PDF form on a CD. Once we receive your location fee payment, we will complete our work to process your request."

The news comes as it's revealed 1000 people arranging to march in London to protest at Mr Avery's innocence.
