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.

Chauvin further alleges that Schaetzel reached out to his trial attorney, Eric Nelson, in 2021, as well as the judge and prosecution in his state-court murder trial, but that Nelson never told him about the pathologist or his ideas. He also alleges that Nelson failed to challenge the constitutionality of the federal charge.

But Chauvin claims in his motion that no jury would have convicted him if it had heard the pathologist’s evidence
