Making a Murderer's Steven Avery Says He'll Pay for His Own Extensive Forensic Testing to Prove His Innocence

Steven Avery is putting his money where his mouth is.

The subject of the hit Netflix docu-series Making a Murderer filed a new 45-page motion asking for "post-conviction testing of physical evidence" since "considerable progress has been made in forensic DNA methods, procedures and tests" since the 2007 murder trial of Teresa Halbach.

The motion also adds that Avery is willing to pay for the extensive testing himself. His lawyers explain that they are formally requesting the "most comprehensive, thorough and advanced forensic testing ever requested by a criminal defendant in the State of Wisconsin" be put into action.

In the court documents, obtained by E! News, Avery's team asks that "body fluid source testing" be performed to possibly " identify the source of the bodily fluids found on the victim's vehicle key and hood latch."

Additionally, Avery is seeking radiocarbon testing that could potentially "establish the age of Mr. Avery's blood found in the victim's vehicle and determine, based on age, if the blood was planted."

His lawyers also as that advanced DNA testing take place on new evidence that has yet to be screened in the case, as well as pre-existing evidence that was tested back during the trial almost a decade ago.

This latest motion comes on the heels of the news that Avery's nephew Brendan Dassey's conviction was overturned.

A judge ordered that Brendan be "released from custody unless, within 90 days of the date of this decision, the State initiates proceedings to retry him."
