Kathleen Zellner has gotten a reputation for helping those wrongfully convicted of crimes. Zellner, a suburban Chicago attorney, is representing Steven Avery in his attempt to get his conviction overturned in the 2005 murder of Teresa Halbach. The case was explored in the 2015 Netflix docuseries "Making a Murderer."

Zellner awaits the results of independent lab tests of nine pieces of evidence in the case. Last summer, she said she would file a formal petition asking a judge to overturn Avery's conviction after the testing was completed. That testing was scheduled to conclude in March.

On March 18, Zellner posted on Twitter: "To all the skeptics, doubters & haters just be patient because we are really going to make you mad."
