Making a Murderer new evidence

In the next 30 days, Steven Avery’s attorney Kathleen Zellner claims she will present new forensic evidence that proves his innocence. 

Making a Murderer was the show that cruelly took over our lives and turned us into crime solving novices as we spent our nights trying to piece together exactly what happened to Teresa Halbach.

The popular Netflix documentary is a lot of things, gripping, enraging, heartbreaking and downright enthralling. Now there has been a huge twist in proving Steven Avery’s innocence. Avery’s new hot shot lawyer Kathleen Zellner is claiming she will present new forensic evidence that proves his innocence within the next 30 days. 

The key piece of new evidence Zellner will present is luminol testing. 


The Bureau of Criminal Apprehension says luminol testing is,

The search for the presence of blood at a crime scene is normally done by close visual examination. The possibility exists, however that blood may be present in amounts too little to see with the unaided eye, or that the blood at the scene had been ‘cleaned up’ prior to the arrival of the crime scene team. Scientists can take advantage of the luminol reaction to locate potential blood evidence that would be undetectable through visual examination.” 

Essentially used to detect blood which is NOT visible to the naked eye. 

The reason that this luminol testing is so important is because, Zellner believes that this testing will prove the absence of Teresa’s blood from key areas of the Avery’s property, proving that Teresa Halbach was not killed in Stephen’s trailer or his garage. Which we all know was essential to the State’s case against Avery. 

Zellner says, “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.” 

There seems to be a lot of movement in the Avery camp with a source telling The Mirror that, 

“Steven’s family have been instructed not to speak to the press. While Kathleen is very happy and appreciative of the growing campaign to have him released she is now taking complete control of the situation.”

“She is working with her own team of lawyers, experts and with Steven’s previous lawyers and with his family to ensure that they can present the best possible case.”
