Nelson also cited the autopsy conducted on Floyd that found fentanyl and methamphetamine in his system, a combination of drugs Nelson says is known as a speedball. He noted that the Hennepin County Medical Examiner's post-mortem report showed Floyd had arteriosclerotic and hypertensive heart disease, hypertension and sickle cell trait. Floyd also purportedly told the officers that he had contracted COVID-19 and was still positive for the virus at the time of his death, a claim confirmed by his autopsy.
"Put simply, Mr. Floyd could not breathe because he had ingested a lethal dose of fentanyl and, possibly, a speedball. Combined with sickle cell trait, his pre-existing heart conditions, Mr. Floyd's use of fentanyl and methamphetamine most likely killed him," Nelson argued. "Adding fentanyl and methamphetamine to Mr. Floyd's existing health issues was tantamount to lighting a fuse on a bomb."
It's also called felony murder. To prove this count, prosecutors had to show that Chauvin killed Floyd while committing or trying to commit a felony - in this case, third-degree assault. They didn't have to prove Chauvin intended to kill Floyd, only that he intended to apply unlawful force that caused bodily harm.
