Maryland's former chief medical examiner testified in the George Floyd trial on Wednesday attesting that Floyd died due to underlying heart disease, not police restraint. In addition to Floyd's heart disease, the medical examiner cited fentanyl, meth, and carbon monoxide from car exhaust as contributing factors in his death.

"In my opinion, Mr. Floyd had a sudden cardiac arrhythmia, or cardiac arrhythmia, due to his atherosclerosis and hypertensive heart disease ... during his restraint and subdual by the police," said Dr. David Fowler. 

He noted, "The substances, the fentanyl, and the methamphetamine. The potential of a carbon monoxide role. And the potential that the paraganglioma was adding adrenaline to this whole mixture, making things even worse."
