Good evening. The 10th day of witness testimony in the Derek Shove and murder trial may prove to be one of the most important.

Two physicians, including a medical examiner who performed the autopsy on George Floyd and ruled his death of homicide,

faced intense questioning from both prosecutors and the defense. A pivotal moment for a defense that rests in large part on trying to create doubt in the mind of at least one juror about the factors that actually contributed to George Floyd's death.

He's never own friends, they can legal experts, for analysis the day is testimony. But first one, take you inside the courtroom or Omar Jimenez tells you the day in court.

In one of the most highly anticipated moments of the trial, you conducted the autopsy on Mr. George Floyd.

I did.

And it been County's chief medical examiner, Dr. Andrew Baker took the stand with respect to Mr. Floyd. You didn't see any damage to the heart muscle.

That's correct. Did you know anything resembling either a pill or pill fragments in the stomach? I did not.

His autopsy report on George Floyd listed the manner of death as homicide, but specifically, cardiopulmonary arrest complicating law enforcement subdue, restraint and neck compression.

I would still classify it as a homicide today. No mention of his fixia and no physical findings to support it either.

In my opinion, the law enforcement subdue, restraint and the neck compression was just more than Mr. Floyd could take by virtue of that those heart conditions.

According to testimony Friday in June 2020, he even told investigators of George Floyd. If he were found dead at home alone and no other apparent causes, this could be acceptable to call in OD or overdose.

But he added at the time, I'm not saying this killed him.

Have you certified deaths as an overdose where the level of fentanyl was similar to the level of fentanyl in Mr. Floyd?

Yes. Does methamphetamine further constrict the vessels and ventricles and arteries?

As a general rule for forensic pathology, methamphetamine is not good for a damaged heart, a heart with coronary artery disease.

Earlier Friday, Dr. Lindsey Thomas, a forensic pathologist and former assistant medical examiner for hennapin county, took the stand.

Did you rule out drug overdose as a cause of death?

Yes. In this case, I believe the primary mechanism of death is asphyxia or low oxygen. There's no evidence to suggest he would have died that night, except for the interactions with law enforcement.

Thomas, even pointing to the autopsy itself, saying ordinarily, that would be all she needed. Not this time.

In this case, the autopsy itself didn't tell me the cause in the inner of death. And it really required getting all of this other additional information, specifically the video evidence of the terminal events to conclude the cause of death.

A cause of death that jurors are now left to wrestle with.
