Steven Avery (born July 9, 1962) is an American man from Manitowoc County, Wisconsin, who served 18 years in prison for a wrongful sexual assault conviction in 1985. Aided by the Wisconsin Innocence Project, he was exonerated when improved DNA testing of evidence found a match with another man. He was released from prison on September 11, 2003.
In 2005, in the middle of depositions for his civil lawsuit against the sheriff's department and district attorney of Manitowoc County, Avery was arrested for the murder of Wisconsin photographer Teresa Halbach. He was convicted in 2007 and sentenced to life imprisonment without parole. The case is under appeal as of January 2016, and a new team of defense attorneys was announced, with Kathleen Zellner taking on his case in conjunction with the Midwest Innocence Project.
Avery's legal trials, particularly the murder case and its related issues, are the focus of the Netflix original documentary Making a Murderer (December 2015), a 10-episode series directed by Laura Ricciardi and Moira Demos.
