Steven Avery's lawyer says authorities released too much information and that Avery may not be able to get a fair trial.
Attorney Dean Strang filed a motion in Manitowoc County Circuit Court. It suggests the statements that Avery's 16-year-old nephew, Brendan Dassey made, about killing Teresa Halbach might not be admissible in court after first being released to the public.
The motion is expected to be taken up when Avery returns to court next Friday for a bond hearing. He and Dassey both face multiple charges.
