'Making a Murderer' Defense Attorney Warns Against Becoming 'Armchair Sleuths'

Attorney Kathleen Zellner is now representing Avery, hoping to help exonerate the Wisconsin native who has risen to new national attention due to the Netflix docuseries Making a Murderer.

Zellner met with Avery last week and both are feeling confident in their ability to prove his innocence through new forensic testing.

"Since 2007 there have been significant advances in forensic testing and so clearly we're going, the clearest way to do this is with scientific testing and that's what we will be asking to do," Zellner told local ABC station WBAY.

She also spoke to Avery's renewed positivity:

"He's extremely positive, because he knows that there's a lot of new forensic testing that can be done, and so he's thrilled that there is new development in technology. So he's very positive."

The new testing Zellner wishes to implement includes looking at "the hood latch, battery cables, where the blood was supposedly found in the car. I want to examine what was not tested in the car that should've been tested, because there's a number of things on the car that obviously would have needed to be tested that weren't."

Zellner also said that they are looking at other suspects who may have murdered Halbach on that fateful 2005 day.

With new developments happening, it's possible that filmmakers Laura Ricciardi and Moira Demos will film another season of Making a Murderer. Demos previously spoke about the possibility of a season 2:

"As we said before, in relation to this story, this story is ongoing, these cases are open," Demos said. "It's real-life so you don't know what's going to happen. We are ready... if there are significant developments, we will be there."

Making a Murderer is available to stream in full on Netflix now.
