"Forensic evidence used to convict Steven Avery for the 2005 murder of Teresa Halbach will soon undergo testing at a laboratory overseen by the person trying to make sure the Manitowoc County man stays in prison. Wisconsin Attorney General Brad Schimel's Department of Justice runs the Wisconsin State Crime Lab. Schimel's office is also trying to make sure Avery's new attorneys aren't successful in getting his conviction overturned. But Schimel said Wednesday that fact will not impact the forensic testing being done here. A total of eight pieces of evidence - including swabs of blood stains, blood flakes and a car key - will all be subjected to testing that wasn't available when Avery was convicted of murdering Halbach in 2007. Avery's attorneys say the crime lab will perform the most comprehensive, thorough and advanced forensic testing ever requested by a criminal defendant in the State of Wisconsin. Schimel is working to assure skeptics it will also be among the most fair testing available. "You can count on - as members of the public - that the crime lab will do this objectively and thoroughly," Schimel told 27 News Wednesday morning. "And that's what we're committed to do. And they will come and do it, endeavoring to find whatever evidence is available." But Schimel added that he knows the Avery case well, and can't imagine the tests will produce any new results. Most of the evidence is from Halbach's SUV, which was found on Avery's Manitowoc County property in 2005. That evidence was used to ensure Avery's conviction, but attorney Kathleen Zellner - who is handling his appeal - believes much of the blood evidence was planted and that the new tests will show that."
