The defense continued to present its case in the murder trial of Derek Chauvin, the former officer accused of killing George Floyd.
A forensic pathologist testified Wednesday that Floyd's death was caused by several factors including drug use, heart disease, and a possible carbon monoxide poisoning from auto exhaust.
Dr. David Fowler said he believes Floyd ultimately died of a sudden heart rhythm problem.
That contradicts what we've heard from several other medical experts, who say Floyd died from a lack of oxygen.
"So in my opinion, Mr. Floyd had a sudden cardiac arrhythmia, or cardiac arrhythmia, due to his atherosclerotic and hypertensive heart disease, or – you can write that down multiple different ways – during his restraint and subdual by the police – or restraint by the police," Fowler said.
