Tampering of evidence is being suspected in the case of Making a Murderer’s Steven Avery, highlighting that the evidence may not have protected in the right manner by the police.


A video released by Sussex Police refers to the evidence of Avery’s blood, which is believed to have been tampered with. Questions arise citing Manitowoc County law enforcement’s lack of protection towards the evidence, according to Crime Scene Investigator Chris Gee.

“It’s all about trying to give evidence as much integrity as possible,” he said. “Manitowoc County law enforcement may not have done everything in their power to properly protect the evidence, leaving some important unanswered questions.”

Gee questioned the integrity of the evidence after it was discovered that there was no exhibit label on the vial of blood. This exhibit label, he said, would give information and details regarding where, and for what purpose, was the bag opened. In addition, it would feature the signature of the person who opened the bag.

“The EDTA bottle that we saw in the Steven Avery case didn’t seem to have an exhibit label with it,” he said. “The exhibit label will have all the details about who seized it, what time, where it was seized.” The fact that the bag was opened suggests it has been tampered.

“Evidence bags are essential to all crime scenes,” Gee said, as reported by Mirror.co.uk

Speaking to the students and staff of Griffith College, creators of the show Making a Murderer, Laura Ricciardi and Moira Demos, noted the number of wrongful convictions across the United States is escalating, as reported by Irish Times.

The show chronicles the case of Steven Avery, who was wrongfully convicted for rape and spent 18 years in prison before he was released. Consequently, he filed a $36 million wrongful conviction lawsuit against the county and the sheriff. But soon thereafter, he was charged with the murder of Teresa Halbach.

Addressing the vial of blood, Gee said it “looked suspicious.”

“If you look carefully, there’s blood in between the stopper and the glass, which you can only get if the stopper was taken out,” he said. “That looked suspicious.”
