New Lawyer Hopes to Use "Advanced Luminol Testing to Exonerate" Steven Avery

New details in Steven Avery's upcoming appeal have emerged. Avery, the subject of Netflix's true crime docu-series Making a Murderer, is currently serving a life sentence for the 2005 murder of photographer Teresa Halbach. Now, Avery's new attorney Kathleen Zellner says she plans to appeal, and it's been announced that the case will utilize "advanced luminol testing to exonerate Avery."

Zellner, who specializes in wrongful conviction cases, plans to bring new evidence forth in an appeal set for next month. According to the Bureau of Criminal Apprehension in Minnesota, "The light, or luminescence, emitted in the luminol reaction is thought to result when an oxidizing agent, such as blood, catalyzes the oxidation of luminol by hydrogen peroxide in a basic solution." As seen on crime shows such as CSI, if blood is present, it will usually be easily visible thanks to the luminol test.

It is Zellner's hope that the testing will prove the absence of Halbach's blood from any of the areas thought to be crime scenes on Avery's property. "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," Zellner said in a statement to TheWrap.

Fans of the show will recall that DNA evidence is what ultimately exonerated Avery of his first 18-year stint in jail for sexual assault. The plans to use advanced luminol testing were first announced on the Making a Murderer official Twitter account.

Earlier last month, Dean Strang, Avery's defense attorney in the original trial, said that there was a "mass" of possible new evidence leads coming in from people who had seen the show. "Leads, ideas [and] possibilities that have arrived in a mass from emails and calls since the film came out," he said.

Making a Murderer is now available to streaming on Netflix. It sparked heated debates around the world following its initial release in December.
