Read The Letter Steven Avery Wrote To His Supporters From Behind Bars

On Friday, Kathleen Zellner — the lawyer representing Steven Avery of “Making A Murderer” — tweeted a picture of a letter written by her client from behind bars.

The short letter, addressed to Avery's supporters, reads:

I want every forensic test possible done [because] I am innocent.

Avery, who was convicted of the 2005 murder of photographer Teresa Halbach, is scheduled to speak in front of the Wisconsin Court of Appeals on February 11. Zellner, who signed on as Avery's legal counsel in January, says:

We are continuing to examine every aspect of Mr. Avery's case and all of his legal options. We are confident Mr. Avery's conviction will be vacated when we present the new evidence and results of our work to the appropriate court.

The “evidence” Avery plans to present includes allegations of police misconduct, illegal searches and corruption designed to frame him for Halbach's murder. Avery also claims he was denied the right to due process, a direct violation of constitutional rights.

Avery was falsely convicted once before, in 1985.  He spent 18 years in jail before DNA testing exonerated him from any wrongdoing.
