That article is from 2021 - here is what I have in my notes about his appeal for new State trial plus his Federal case appeal - all rejected/denied.
7/19/23 Update: Chauvin will take the appeal of his state murder conviction to the Superior Court after Minnesota’s top court denied the request to hear his petition. “We will petition the United States Supreme Court via a Writ of Certiorari & ask them to review the lower court’s decision on behalf of Mr. Chauvin,” attorney Gregory M. Erickson said in a statement Wednesday.
11/13/23 Update: Chauvin is making another attempt to overturn his federal civil rights conviction in the 2020 murder of George Floyd, saying new evidence shows that he didn’t cause Floyd’s death. In a motion filed in federal court Monday, Chauvin said he never would have pleaded guilty to the charge in 2021 if he had known about the theories of a Kansas pathologist with whom he began corresponding in February. Chauvin is asking the judge who presided over his trial to throw out his conviction & order a new trial, or at least an evidentiary hearing. Chauvin, who is serving a 21-year sentence at a federal prison in Arizona, filed the request without a lawyer. He says Dr. William Schaetzel, of Topeka, Kansas, told him that he believes Floyd died not from asphyxia from Chauvin’s actions, but from complications of a rare tumor called a paraganglioma that can cause a fatal surge of adrenaline. The pathologist did not examine Floyd’s body but reviewed autopsy reports. A federal appeals court has rejected Chauvin’s requests for a rehearing twice. He’s still waiting for the U.S. Supreme Court to decide whether it will hear his appeal of his state court murder conviction.
11/20/23 Update: The Supreme Court has rejected Chauvin’s appeal of his conviction for second-degree murder in the killing of Floyd. Chauvin is separately appealing his conviction on federal civil rights charges.
