The medical examiner who performed George Floyd's autopsy is set to testify in Derek Chauvin's trial

Crucial testimony in the trial of former police officer Derek Chauvin is expected Friday when the medical examiner who performed George Floyd's autopsy takes the stand.

Prosecutors intend to call Hennepin County Chief Medical Examiner Dr. Andrew Baker, who ruled Floyd's death last May a homicide, identifying the cause as "cardiopulmonary arrest" that occurred during "law enforcement subdual, restraint, and neck compression." Baker's testimony will come on the 10th day of Chauvin's trial, the culmination of a week filled with expert testimony by not only medical experts, but also policing experts who testified Chauvin violated policy and used excessive force on Floyd.
