Hennepin County Chief Medical Examiner Dr. Andrew Baker ruled Floyd’s death last May a homicide and identified the cause as “cardiopulmonary arrest” that occurred during “law enforcement subdual, restraint, and neck compression” – all findings he stood by in court on Friday.
Floyd had hypertensive heart disease, Baker said, “meaning his heart weighed more than it should.” This meant Floyd’s heart needed more oxygen than a normal heart and was “limited in its ability” to provide more oxygen when there was a demand for it.
In the midst of an altercation and being held to the ground, adrenaline would pour into the body, Baker said, making the heart beat faster.
“In my opinion, the law enforcement subdual, restraint and the neck compression was just more than Mr. Floyd could take by virtue of those heart conditions,” he said.
