“The documentary Making a Murderer left out several facts. I’m here to set the record straight,” says Ken Kratz, former district attorney of Calumet County, Wisconsin, who was featured in the series.

Making a Murderer, Netflix’s popular docuseries, focuses on Steven Avery, a man exonerated by DNA in a rape case and set free after 18 years in prison, only to be arrested and charged with a grisly murder two years later. In 2007, Avery was convicted and sentenced to life in prison without the possibility of parole for killing Teresa Halbach, a photographer who had done work for Avery’s family business. When Avery was arrested, he was embroiled in a $36 million civil lawsuit against the county for wrongful conviction in the rape case – and many believe law enforcement framed him for Halbach’s murder in retaliation for his lawsuit.

However, Kratz, the prosecutor in Avery’s 2007 trial, says he believes there’s ample evidence to prove that Avery killed Halbach.

“Blood was found in six different places in Teresa’s car, deposited in several different ways, including by gravity-- but also by contact transfers,” Kratz explains on Monday’s episode of Dr. Phil.

Kratz also references Halbach’s car key, which he claims was found in Avery’s bedroom. “The documentary made it seem like the key was planted. They suggested it wasn’t found until the sixth or seventh search. In reality, this key was found on the first thorough search of the bedroom,” he says.

In Making A Murderer, Avery’s attorney claims the blood and car key were planted.

“Certain editing tactics like cherry-picking or omissions -- it seemed as if the documentary fabricated the truth,” Kratz says.
