Prosecutors have charged Steven Avery with the murder of Teresa Halbach.
The Mishicot man is also charged with mutilating her corpse.
A criminal complaint filed Tuesday in Manitowoc says a state Justice Department DNA expert has preliminarily identified DNA from charred human remains found on Avery's property as matching that of the victim's DNA.
Avery is expected in Manitowoc County Circuit Court. He has repeatedly denied he had anything to do with Halbach's disappearance or murder.
Investigators searching for Halbach say they found human teeth and bones in the burn pit behind Avery's garage. Prosecutors say they found Avery's blood in Halbach's S-U-V discovered on the Avery family property. And they say Avery's DNA was found on the ignition key to Halbach's vehicle.
Halbach had an appointment to photograph some cars at the Avery salvage yard October 31st, the day she disappeared.
Avery is the man who was freed from prison two years ago after he spent 18 years behind bars for a sexual assault it was later learned he didn't commit. He was freed at the Stanley Prison in Chippewa County.
Avery has repeatedly told reporters he believes he's being set up because of his pending 36 million dollar lawsuit against Manitowoc County for his wrongful conviction.
