'Making A Murderer' Spoilers, News & Update: Swedish Blood Test Proves Stephen Avery Innocence? State Pushes Brendan Dassey Conviction

A group of researchers from the Karolinska Institutet in Sweden is looking to do more blood tests on the evidence that was presented against Steven Avery in "Making a Murderer." Co-accused Brendan Dassey, who is due for release from prison for wrong conviction, might not get out. The state of Wisconsin is reportedly pushing to confirm the original ruling on his case in their appeal.

The research team at the Karolinska Institutet hopes to find out whether Steven Avery was wrongly convicted for murdering Teresa Halbach, as told on "Making a Murderer." After having viewed the documentary in 2015, Kirsty Spalding of the medical university team was said to have gotten in touch with Steven Avery's lawyer to offer their services.

According to The Local Sweden, Kirsty Spalding plans to use a radiocarbon dating technique for examining the evidence against Steven Avery in "Making a Murderer." The test can apparently tell how old the blood is, which could determine whether the evidence was planted or not. The site further reports that it's not known if the test was already done but the lawyers of "Making a Murderer" subject Steven Avery are in touch with Spalding and her team.

Meanwhile, Steven Avery's nephew, Brendan Dassey, is supposed to be released from prison soon. A court ruled last August that his testimonies were coerced by authorities, as shown in "Making a Murderer" Season 1. Thus, the first conviction was overturned.

However, the state of Wisconsin has filed an appeal in September and it is pushing to confirm the original conviction of "Making a Murderer" subject Brendan Dassey. Wisconsin Attorney General Brad Schimel has filed a brief on Wednesday, Oct. 19, to convince the court to let the first conviction stick, NBC 26 reports.

An analyst believes that federal court judges will go with the overturn decision, in which case, the state could elevate the appeal to the Supreme Court. "Making a Murderer" subject Brendan Dassey will not be released from prison as long as an appeal is in place and sometimes deciding on this can take months.

"Making a Murderer" documentary filmmakers are closely following what is going on in this case as part of its second season release. This real-life crime drama is definitely far from over.
