FRANK VASCELLARO: The cause of George Floyd's death took center stage today during the trial of former Minneapolis police officer Derek Chauvin.

AMELIA SANTANIELLO: Three experts took the witness stand to discuss Floyd's final moments. A warning, some of the images are disturbing. As WCCO's Jennifer Mayerle explains, two doctors agreed that one thing led to Floyd's death.

JENNIFER MAYERLE: One of the foremost pulmonary experts in the country stated his opinion on what caused George Floyd's death.

MARTIN TOBIN: Mr. Floyd died from a low level of oxygen. And this caused damage to his brain that we see. And it also caused a PEA arrhythmia that caused his heart to stop.

JENNIFER MAYERLE: During detailed testimony, Dr. Martin Tobin points out where Floyd used his knuckles to try to raise up to get air into his lungs. Another moment where a lack of oxygen to the brain made his leg kick. And during a slow-motion video that may be hard to watch, the doctor goes over what he says are Floyd's final moments.

MARTIN TOBIN: You can see his eyes. He's conscious. And then you see that he isn't.

That's the moment the life goes out of his body.

JENNIFER MAYERLE: He testified former officer Derek Chauvin stays on Floyd's neck for another three-plus minutes.

MARTIN TOBIN: A healthy person subjected to what Mr. Floyd was subjected to would have died as a result of what he was subjected to.

JENNIFER MAYERLE: The defense countered with drugs found in Floyd's system.

ERIC NELSON: Is it fair to say that you would expect the peak fentanyl respiratory depression within about five minutes?

MARTIN TOBIN: Right. I mean, obviously, it would depend on how much of it was ingested.

JENNIFER MAYERLE: Another medical expert agreed with Dr. Tobin that Floyd died from a lack of oxygen.

BILL SMOCK: From his chest, pressure on his chest and back, he gradually succumbed to lower and lower levels of oxygen until it was gone and he died.

JENNIFER MAYERLE: Dr. Bill Smock also dismissed other causes of death, including a drug overdose. Jennifer Mayerle, WCCO 4 News.

AMELIA SANTANIELLO: A scientist also testified that Floyd had meth and fentanyl in his system. He called the amount low, and said that he did not think Floyd would have felt intoxicated. We expect to hear from the medical examiner tomorrow. You can watch the trial streaming all day on CBSN Minnesota. Just download our app or watch it live on WCCO.com.
