Floyd should've received immediate first aid -defense expert

Dr. David Fowler, who was Maryland's chief medical examiner until his retirement in 2019, also told the jury he believed exhaust fumes from the police car next to which Chauvin pinned Floyd to the road may also have contributed to Floyd's death in May 2020.

Chauvin kept his knee Floyd's neck for more than three minutes after Floyd stopped breathing, which his own expert witness agreed was wrong.

"Are you critical of the fact that he wasn't given immediate medical care when he went into cardiac arrest?" prosecutor Jerry Blackwell asked.

"As a physician, I would agree," Fowler replied.
