Steven Avery's attorney has filed a 1,272-page notice for post conviction relief in Manitowoc County.

Attorney Kathleen Zellner appeared in person to file the document Wednesday rather than providing an electronic filing.

Avery is serving a life sentence for the Halloween 2005 murder of freelance photographer Theresa Halbach. Avery is appealing his conviction with Zellner's help.

Zellner says if the court won't release him from prison based on these arguments, as an alternative he's entitled to a new trial in the interest of justice.

Her filing boils down to five arguments:

Ineffective defense counsel

Zellner claims Avery's trial attorneys, Dean Strang and Jerome Buting, failed at representing their client effectively by not putting expert witnesses on the stand to talk about DNA and blood spatter evidence.

Ethical violations by the prosecutor

She accuses special prosecutor Ken Kratz of ethical violations, fabricating evidence and destroying Avery's reputation.

Brady violation

It argues a Brady violation, referring to a U.S. Supreme Court case that ruled prosecutors violated a defendant's due process by suppressing evidence that was favorable to the defendant who requested it

New evidence

Zellner's motion breaks down the new scientific testing she had completed on evidence on the theory Avery's DNA was planted.

Zellner says the bullet fragment found in Avery's garage was not shot through Halbach's head.

She says a microscopic examination of the hood latch on Halbach's RAV 4 shows Avery's DNA did not get there by touching, meaning he didn't open the hood of the car.

And Avery's DNA found on her car key included too many cells to be transferred by simply holding the key, and could have been planted using something like Avery's toothbrush.

Included in the new evidence was testing called "brain fingerprinting," a technique to determine whether specific information is stored in a person's brain. A federal report suggests that testing has not been proven effective or useful, but according to the motion, through brain fingerprinting Zellner's expert determined Avery's brain didn't show that he knew specific details about the crime.

The Wisconsin State Crime Lab in Madison has been analyzing forensic evidence used to convict Avery.

Eight pieces of evidence — including swabs of blood stains, blood flakes and a car key — are subject to testing. Most of it is from Halbach’s SUV found on Avery’s Salvage property in 2005. The testing is more advanced than what was available when Avery was convicted of murdering Halbach in 2007.

Allowable claim

Zellner also argues to the court that Avery's previous post-conviction motions do not procedurally bar him from bringing this claim.

In her motion, Zellner tries to pin Halbach's murder on an ex-boyfriend, claiming he had motive and opportunity and that he misled investigators about damage on Halbach's vehicle.

Zellner tweeted that Avery's jury "did not hear evidence" on the ex-boyfriend.

The Wisconsin Department of Justice says they are "confident" that the motion will be rejected.

Kratz provided this statement to Action 2 News:

Strang declined to comment until he's seen the filing and read it over.

We also reached out to Buting and the state attorney general's office, which is representing the state in the appeal. We have not received responses.

Steven Avery's brother Chuck told us, "Justice will be served."

As this case drags on, Manitowoc County Executive Bob Ziegelbauer said we can't forget about Halbach and her family.

"I am just concerned and have a very high degree of sympathy for the Halbach family because it comes up again and it will be on the TV and in the paper for a long time again and their loss is every day and it’s too bad," said Ziegelbauer.

The case became an international sensation after the docu-series "Making A Murderer" premiered on Netflix in December 2015. Filmmakers presented the possibility that Avery and his nephew Brendan Dassey were wrongly convicted. Our Action 2 News crew spotted the "Making a Murderer" documentary crew at the courthouse on Wednesday. Netflix's Vice President of Original Content announced in January that there would be new episodes later this year.

Avery's nephew Brendan Dassey was also convicted in Halbach's murder. Dassey's conviction was overturned after a judge ruled his confession had been coerced, but Dassey is still in prison while the state appeals that ruling.

On Wednesday, Zellner's former client Ryan Ferguson tweeted, "The reckoning has come! @ZellnerLaw files a bombshell post-conviction petition in the #stevenavery case." Zellner helped free Ferguson after he spent 10 years in prison for a murder he did not commit.
