A Wisconsin inmate has apparently confessed to the killing of Teresa Halbach, whose murder case was documented in the 2015 hit Netflix series “Making a Murderer.” But filmmakers say the confession didn’t come from Steven Avery or Brendan Dassey, who have been in prison for the crime for more than a decade.

Avery, 57, and his nephew, Dassey, 29, are currently serving life sentences for the murder of 25-year-old Halbach, who was killed on Halloween in 2005 after visiting Avery’s property in Wisconsin.
