Live Updates: Testimony enters third week in Derek Chauvin trial

Testimony is entering its third week in the trial of Derek Chauvin, the fired Minneapolis officer charged in George Floyd's death, after medical experts and forensic pathologists testified last week about Floyd's cause of death. 

How Floyd died has been a key point of contention at the trial. Prosecutors argue he died of oxygen deprivation under the weight of officers pinning him down during the fatal May 2020 arrest, while the defense argues the drugs he ingested combined with underlying heart disease caused a fatal heart arrhythmia. On Friday, Hennepin County medical examiner Dr. Andrew Baker, who conducted Floyd's autopsy, testified that heart disease and drugs contributed to but didn't directly cause Floyd's death.
