George Floyd died from a low level of oxygen from being pinned facedown by Derek Chauvin for more than nine minutes with his hands handcuffed behind him, a leading pulmonologist told the former officer's murder trial.
Dr Martin Tobin, a world-leading lung and critical care specialist, said Mr Floyd's breathing was too shallow to take in enough oxygen, which in turn damaged his brain and caused an abnormal heart rhythm that made his heart stop.
