Preliminary results from an independent autopsy commissioned by George Floyd's family found that his death in the custody of Minneapolis police officer Derek Chauvin was "homicide caused by asphyxia due to neck and back compression that led to a lack of blood flow to the brain," according to a statement from the family's attorney.
The latest: An updated official autopsy released by the Hennepin County medical examiner also determined that the manner of Floyd's death was "homicide," ruling it was caused by "cardiopulmonary arrest complicating law enforcement subdued, restraint, and neck compression."
Louisville Mayor Greg Fischer fired the city's chief of police Steve Conrad after it was discovered that police officers had not activated their body cameras during the shooting of David McAtee, a local black business owner who was killed during protests early Monday morning.
Why it matters: Mandatory body camera policies have proven to be important in efforts to hold police officers accountable for excessive force against civilians and other misconduct. Those policies are under even greater scrutiny as the nation has erupted in protest over the killing of black people at the hands of police.
