Jerry Buting, who defended Steven Avery in the murder trial of Teresa Halbach, the story told in the hit Netflix documentary series Making a Murderer, claims the state prosecutor at the time, Ken Kratz, prevented his client from getting a fair trial.

“He never had a right to have a fair trial after Ken Kratz goes on live television and pollutes the entire jury pool from the state of Wisconsin, telling this fabricated story about this bloody rape, torture, and murder and mutilation of her body, when there was no physical evidence that supported it, ever,” Buting tells Dr. Phil on Monday’s episode.

“Tell Dr. Phil why you wanted to keep the case in Manitowoc. You had the choice to move it,” Kratz says to Buting.

“Because the entire state was polluted,” Buting retorts.

“Do you think he ran red lights to get this conviction?” Dr. Phil asks Buting, referring to Kratz.

“Absolutely,” Buting replies.

In 2007, Avery was convicted and sentenced to life in prison without the possibility of parole for killing Halbach, a photographer who had done work for Avery’s family business. When Avery was arrested in 2005, he was embroiled in a $36 million civil lawsuit against the county for wrongful conviction in an unrelated rape case, and many believe law enforcement planted evidence to frame him for murder in retaliation for suing.
