George Floyd died from low oxygen levels, respiratory expert testifies

George Floyd died from low oxygen levels while being restrained by ex-Minneapolis cop Derek Chauvin — and a healthy person would have suffered the same fate if put in the same position, a world-renowned respiratory expert testified Thursday.

Dr. Martin Tobin delivered the damning testimony on the ninth day of Chauvin’s trial for the May 25, 2020, killing of Floyd, who was arrested for passing a counterfeit $20 bill.

“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,” Tobin said.
