A judge has granted permission to lawyers for Derek Chauvin to have samples from George Floyd examined as part of the former Minneapolis police officer’s efforts to challenge his conviction on a federal civil rights charge stemming from Floyd’s death in 2020.

Schaetzel suggested that Floyd died of high levels of catecholamines, a neurohormone associated with the flight-or-fight response, or Takotsubo myocarditis, a heart condition caused by intense emotional or physical experiences.
