In March 2006, Dassey, then 16, told investigators he had helped his uncle, Steven Avery, rape and murder photographer Teresa Halbach on Oct. 31, 2005. But he later recanted, claiming the confession had been coerced.
On the day of the confession, lead investigators Tom Fassbender and Mark Wiegert pulled Dassey out of school and questioned him alone for hours. During that questioning, Dassey told investigators he had helped Avery kill Halbach, saying that they shot her in the head and burned her body at a bonfire on the Avery property later that evening.

Calumet County Prosecutor Ken Kratz called a press conference shortly after investigators secured the confession, saying that Dassey described in detail Halbach's brutal assault and slaying. From the portions of the confession shown in the Netflix series, however, Dassey describes little. Many believe he was led by Fassbender and Wiegert, who repeatedly question him until the teen gives them a confession.
In a recorded exchange with his mother, Barb Janda, following the confession, Dassey says, "They got in my head." The teen later denied that he ever saw Halbach and said he had nothing to do with her murder.
