dassey recanted his statements.ery's trial, the judge dismissed the rape charge against him and didn't allow any of those allegations about avery's treatment of women, saying they didn't prove anything about teresa's murder. and avery was never charged with assaulting his ex-fiancee or with raping the teen. to this day, he denies all the allegations. and those handcuffs and shackles, no evidence ever linked them to teresa. still, in the spring of 2007, juries convicted both dassey and avery of murdering teresa. they were each sentenced to life in prison. >> you are probably the most dangerous individual ever to set foot in this courtroom. >> it seemed like the avery saga had ended. but eight years later, "making a murderer" would put fassbender, kratz, and their entire team in the hot seat. >>> coming up -- >> did they plant evidence? >> sure, they did. >> was steven avery framed? >> is it possible that that blood could have been planted? >> when "dateline" continues. looks like they picked the wrong getaway driver.
