Pulmonologist Dr. Martin Tobin testified this morning in the trial against former Minneapolis police officer Dereck Chauvin, the man accused of killing George Floyd. He said, “Mr. Floyd died from a low level of oxygen. And this caused damage to his brain that we see, and it also caused a PEA [pulseless electrical activity] arrhythmia that caused his heart to stop.”
