Derek Chauvin asks Minnesota Supreme Court to review his murder conviction, weeks after appeals court denied his request for a new trial

Former Minneapolis police officer Derek Chauvin has asked the state Supreme Court to review his murder conviction for the 2020 killing of George Floyd, a month after an appeals court denied his previous request for a new trial, court documents show.

In the documents, filed Wednesday, Chauvin’s attorneys cited many of the same reasons from their previous filings to the Minnesota Court of Appeals – arguing again, among other things, that the district court deprived the former officer his right to a fair trial when they denied his request for a change of venue, despite “pervasive adverse publicity.”

Chauvin’s attorneys said these reasons were grounds for a new trial and asked the state’s highest court to grant a review of the appeals court decision. The Minnesota Supreme Court has not yet said if it will review the decision.

Chauvin was found guilty in April 2021 of second-degree unintentional murder, third-degree murder and second-degree manslaughter. He was sentenced to 22 and a half years in prison, which exceeded Minnesota’s sentencing guideline range of 10 years and eight months to 15 years.

Chauvin later pleaded guilty to federal charges of violating Floyd’s civil rights and was sentenced to 21 years in prison to run concurrent with his state sentence.

Body camera and bystander video that captured the final moments of Floyd’s life on May 25, 2020, shows Chauvin kneeling on the 46-year-old Black man’s neck and back for more than nine minutes as Floyd gasped for air and told officers, “I can’t breathe.”

Floyd’s death ignited prolonged protests across the country over police brutality and racial injustice. An investigation by the state Department of Human Rights launched a week later found Minneapolis and its police department engaged in “a pattern or practice of race discrimination,” according to its 2022 report.

Chauvin is currently incarcerated at the Federal Correctional Institution in Tucson, Arizona, according to the Federal Bureau of Prisons website. The prison is a medium security federal correctional institution with a detention center, according to the website.

Attorney cites publicity, protests, and prosecutorial misconduct in appeal

In his April 2022 filing to the state Court of Appeals, Chauvin’s attorney William Mohrman listed more than a dozen aspects of the case and trial that he argued tainted the proceedings and rendered them “structurally defective,” CNN previously reported.

The list included extensive pretrial publicity and protests outside the courthouse, as well as the city’s announcement during jury selection that it would pay a $27 million settlement to Floyd’s family.

Chauvin and his attorney also asked the appeals court to review whether the venue should have been changed, the jury fully sequestered, or the trial delayed because of pretrial protests and media coverage.

The appeal to the lower appeals court also accused prosecutors of misconduct, alleging the state’s attorneys failed to properly disclose discovery information and adequately prepare prosecution witnesses.

In the 50-page decision affirming Chauvin’s conviction last month, a three-judge panel of the Minnesota Court of Appeals upheld the conviction, holding in part that Chauvin failed to show actual prejudice.

At the time of Chauvin’s sentencing in June 2021, Judge Peter Cahill wrote in a memorandum that the case warranted a harsher sentence because Chauvin “abused his position of trust and authority” and treated Floyd “without respect and denied him the dignity owed to all human beings.”
