Derek Chauvin trial: police chief to testify against former officer in 'remarkable move'

Chief Medaria Arradondo's testimony over George Floyd's death may be unprecedented, experts say

As the prosecutor Jerry Blackwell addressed the jury for the first time in the murder trial of Derek Chauvin last week, he reeled off a list of witnesses expected to testify: from eyewitnesses who watched as the former officer held his knee on George Floyd's neck for nine minutes and 29 seconds, to forensic pathologists, use of force experts and members of the Minneapolis police department.

Among the most significant on this long list was the most senior member of that department, Chief Medaria Arradondo.
