Expert blames Floyd’s death on heart problem
Testimony contradicts previous opinions
MINNEAPOLIS – George Floyd died of a sudden heart rhythm problem due to his heart disease while being restrained by police, a retired forensic pathologist testified for the defense Wednesday at former Officer Derek Chauvin’s murder trial, contradicting experts who said Floyd succumbed to a lack of oxygen from the way he was pinned down.
Dr. David Fowler, a former chief medical examiner for the state of Maryland and now a member of a consulting firm, said the fentanyl and methamphetamine in Floyd’s system, and possible carbon monoxide poisoning from auto exhaust, were contributing factors.
“All of those combined to cause Mr. Floyd’s death,” Fowler said on the second day of the defense case.
He also testified that he would classify the manner of death “undetermined,” rather than homicide as the county’s chief medical examiner ruled. Fowler said the death had too many conflicting factors, some of which could be ruled homicide and some that could be considered accidental.
Chauvin attorney Eric Nelson is trying to prove that the 19-year Minneapolis police veteran did what he was trained to do and that Floyd died because of his illegal drug use and underlying health problems.
Prosecutors say Floyd died because Chauvin’s knee was pressed against Floyd’s neck or neck area for 91⁄2 minutes as the 46-year-old Black man lay pinned to the pavement on his stomach in May, his hands cuffed behind his back.
Fowler listed a multitude of factors: Floyd’s narrowed arteries, his enlarged heart, his high blood pressure, his drug use, the stress of his restraint, the vehicle exhaust, and a tumor or growth in his lower abdomen that can sometimes play a role in high blood pressure by releasing “fight-or-flight” hormones.
Fowler said all of those factors could have acted together to cause Floyd’s heart to work harder and suddenly stop.
Previous witnesses have noted that a sudden heart rhythm problem does not necessarily produce visible signs on autopsy but can be inferred from circumstances such as a victim suddenly clutching one’s chest and collapsing.
Nelson questioned Fowler about carbon monoxide, which displaces oxygen in the bloodstream of people who breathe it in. Fowler said it could have contributed to oxygen depletion in Floyd, noting that he was facing the tailpipe end of a vehicle. But there is no way to know for sure because, he acknowledged, Floyd’s blood was never tested for carbon monoxide.
Fowler handled a case similar to Floyd’s in Maryland in 2018, when a 19year-old Black man, Anton Black, died after three officers and a civilian pinned him for more than five minutes as they handcuffed him and shackled his legs.
The family brought a federal lawsuit that included Fowler, whose autopsy concluded that the stress of the struggle probably contributed to Black’s death but found no evidence that restraint directly caused it. It also found no evidence of asphyxia, or a lack of oxygen.
