Steven Avery is an American convicted murderer from Manitowoc County, Wisconsin, who had previously been wrongfully convicted in 1985 of sexual assault and attempted murder. After serving eighteen years of a thirty-two-year sentence (six of those years being concurrent with a kidnapping sentence), Avery was exonerated by DNA testing and released in 2003, only to be charged with murder two years later. Avery’s 2003 exoneration prompted widespread discussion of Wisconsin’s criminal justice system; the Criminal Justice Reform Bill, enacted into law in 2005, implemented reforms aimed at preventing future wrongful convictions. On February 20, 2018, Dassey’s legal team, including former Solicitor General of the United States Seth Waxman, filed a petition for a writ of certiorari to the U.S. Supreme Court. On June 25, 2018, certiorari was denied.
