Dr. Andrew Baker testified that Floyd’s present and underlying heart condition was a contributing bring about of his demise it was evidenced by a heart that “weighed more than it need to” and coronary arteries that ended up noticeably narrowed.
“The legislation enforcement subdual and neck compression is just more than Mr. Floyd could choose by advantage of his heart problems,” Baker reported.
In his autopsy report last calendar year, Baker claimed Floyd’s coronary heart and lungs stopped amid “regulation enforcement subdual, restraint and neck compression,” but he did not use the phrase “asphyxia,” or oxygen loss. He ruled the loss of life a homicide.
Friday early morning, the previous Hennepin County healthcare examiner explained to the jury that Floyd died from asphyxia due to officers’ restraint – heading a phase additional than the autopsy.
“This is a death in which equally coronary heart and lungs cease doing work,” reported Dr. Lindsey Thomas, a previous forensic pathologist for the county who educated Baker. “The point is it is because of to regulation enforcement subdual, restraint and compression.”
A household-commissioned autopsy produced close to the exact same time observed Floyd’s loss of life was a murder prompted by “asphyxiation from sustained strain.”

Chief health care examiner particulars conclusions of George Floyd autopsy for jury
Dr. Andrew Baker, the main healthcare examiner for Hennepin County, informed jurors that the “top-line” immediate cause of Floyd’s death remained unchanged now: Floyd’s heart and lungs stopped beating as a end result of currently being subdued, restrained and acquiring his neck compressed by law enforcement officers through their encounter.
For the duration of the autopsy, Baker explained he did not discover any accidents to Floyd’s again, nor any bruises or scrapes. But he discovered “several injuries” to Floyd’s experience that would match Floyd’s experience pinned to the asphalt in the prone position the night time in advance of, Baker stated.
He also famous handcuff marks on his palms and blunt-force accidents on Floyd’s suitable pointed and center fingers.
“These are totally reliable with him remaining in an altercation with somebody,” Baker explained.
All through the evaluation of Floyd’s body and organs throughout autopsy, Baker’s original appear uncovered no true destruction to the mind, lungs or coronary heart – whilst he said there was proof of intense narrowing of coronary arteries, sizeable enough to bring about sudden loss of life in a person.
Continue to, Baker explained, “To the most effective of my awareness, he was generally healthier on May well 25 ahead of the events of that evening.”
He also observed he waited to view video of Floyd’s battle with police right until after his exam: “I did not want to bias my test with any preconceived notions,” Baker explained.
Baker also testified he did not notice deprivation of blood or oxygen to the mind, but famous that “the human being has to endure the anoxic brain injury for a substantial period of time of time just before we can see” any brain cell harm.
Baker reported Floyd’s coronary heart was outside the upper limit of normal for a male of his measurement, contradicting Thomas’ earlier testimony.
“His coronary heart previously desired more oxygen by its size,” but that was minimal because of narrowed coronary arteries, he reported.
Baker said the altercation and suffering of getting pressed versus asphalt would’ve caused an improve in worry hormones like adrenaline that would “ask your heart to defeat more quickly. He added: “It can be likely to request your system for far more oxygen so that you can get by that altercation.”
Baker also reported he located no proof of a tablet or capsule fragments in Floyd’s tummy.
The defense has argued that Floyd’s fundamental coronary heart difficulties and drug use contributed to his loss of life.
For the duration of questioning from defense attorney Eric Nelson, Baker stated he included coronary heart illness, the heritage of hypertension and the prescription drugs in his technique on the loss of life certification mainly because they played a contributory position in Floyd’s loss of life.
“He experienced a cardiopulmonary arrest in the context of law enforcement, subdual, restraint, compression,” Baker said. “It was the tension of that interaction that tipped him in excess of the edge, supplied his fundamental heart disease and its toxicology status.”
Baker noted neck compression is on the “major line” of his lead to-of-demise statement and claimed he imagined Chauvin’s knee was generally on Floyd’s back, aspect or the place in amongst Floyd’s neck. Baker explained he didn’t imagine Chauvin’s knee placement would anatomically slice off Floyd’s respiration, but also acknowledged he was no specialist in examining and reading online video footage.
Prior professionals have testified that Chauvin’s knee was principally on Floyd’s neck by means of the 9 minutes and 29 seconds that Floyd was vulnerable and handcuffed on the ground final May possibly.
Baker explained he did not uncover anatomical evidence to assist the summary of loss of life by asphyxiation, adding that he recalled informing Hennepin County attorneys of that fact.
But he also said that he could not element the impression of the come across with Chauvin on Floyd’s respiratory mainly because he is not a pulmonologist. He frequently referred Nelson to question this kind of concerns to these types of an skilled of the respiratory process.
Also, Baker informed jurors that if Floyd had been identified useless in his locked home with no proof of trauma, he would’ve concluded Floyd died of an overdose.
Nelson’s questioning appeared “to be troublesome” to 1 juror, a Black gentleman, who was found squinting his eyes toward the legal professional and shaking his head a little.
On re-immediate questioning by state’s legal professional Jerry Blackwell, Baker emphasized that the major-line direct lead to of demise stay unchanged now – it really is even now “cardiopulmonary arrest” as a result of Floyd remaining subdued, restrained and his neck compressed by legislation enforcement. Baker mentioned yet again that aspects like Floyd’s drug ingestion or fundamental coronary heart challenges are “contributing triggers.”
“It was my prime line then. It would continue to be my top line now,” Baker said of the legislation enforcement restraint. “I would nevertheless classify it as a murder currently.”
Forensic pathologist: George Floyd died from asphyxia, or very low oxygen
Friday morning, the prosecution referred to as forensic pathologist Dr. Lindsey Thomas as an skilled witness who has reviewed paperwork and videos in the scenario. She also trained Dr. Andrew Baker, the Hennepin County chief professional medical examiner who dominated Floyd’s demise a homicide, and who was predicted to testify afterwards on Friday.
Thomas explained she agreed with Baker’s autopsy results. “In this situation, I consider the principal system of demise is asphyxia, or very low oxygen,” she reported. “This is not a unexpected cardiac dying.”
Thomas entered semi-retirement in 2017 but however does consulting and will work in the healthcare examiner’s workplaces in Reno and Las Vegas. Formerly, she was the medical examiner for many Minnesota counties. She claimed she’s done about 5,000 autopsies and has consulted with other healthcare examiners on about 1,000 more autopsies.
Thomas said Floyd’s autopsy was “seriously terrific for ruling factors out.” She claimed there was no evidence from the autopsy that Floyd experienced ample lung disorder to impair his respiration. He failed to have a heart attack or a stroke, she explained. And the sluggish nature of Floyd’s dying reveals he did not die of a methamphetamine or fentanyl overdose, she said.
“Basically, Mr. Floyd was in a place … wherever he was unable to get plenty of oxygen,” Thomas said, echoing prior testimony by Dr. Martin Tobin and Dr. Bill Smock, other health care professional witnesses referred to as by the prosecution on Thursday. Answering prosecutor Jerry Blackwell, she afterwards emphasised: “There is no evidence to recommend he would have died that night except for the interactions with legislation enforcement.”
The long battle with police developed chemical reactions in Floyd’s physique that induced physiological worry, Thomas reported: “This goes on for minute, after moment, for nine minutes,” she claimed. The physiological stress that final results from that situation will not present up in an autopsy, but could be thought of a contributing cause of death,” Thomas testified.
On cross examination, guide protection lawyer Eric Nelson proposed Floyd’s underlying heart challenges and drug use contributed to his demise.
Prompted by Nelson, Thomas reported the autopsy confirmed Floyd’s coronary heart was enlarged and that Floyd had narrowing of coronary arteries. If Floyd had died at household, with no confrontation with law enforcement, Thomas explained she would likely have concluded that Floyd died of coronary heart disease.
Requested if, in one more hypothetical scenario in which Floyd was found lifeless at household, she would conclude Floyd died of an overdose, Thomas stated she “could think about” it.
Nelson also referenced scientific studies in Canada that discovered people arrested in the prone posture did not die. Thomas appeared skeptical of the examine. She mentioned the vulnerable placement is not inherently harmful “unless there are other variables.”
“I could be laying by the pool in Florida, on my tummy in the prone position, not inherently unsafe?” Nelson stated. “Proper,” explained Thomas.
When prosecutor Jerry Black re-questioned Thomas, he challenged the hypothetical scenarios Nelson experienced . “Aren’t individuals queries a lot like inquiring, Mrs. Lincoln, if we just take John Wilkes Booth out of this,” Blackwell started, only to be stopped by Decide Peter Cahill for posing an argumentative dilemma. Thomas agreed, as a forensic pathologist, she would not pursue a hypothetical problem by taking away aspects that she concluded experienced caused dying.
Blackwell also followed up on Nelson’s pool scenario. “George Floyd was not laying by the pool on his tummy in Florida, was he?” Blackwell asked. “No,” Thomas explained.
Health care provider for prosecution: ‘What Mr. Floyd was subjected to’ would get rid of a healthy human being
Dr. Martin Tobin, a doctor who has been functioning in respiratory physiology for 40 several years, testified Thursday that Floyd died from a “minimal amount of oxygen,” which prompted hurt to his mind and an abnormal heartbeat. Tobin was known as as an expert witness by prosecutors and examined documents and movie in the Floyd case, but he did not conduct an examination of Floyd’s physique.
Tobin mentioned he watched videos of Floyd’s arrests “hundreds of moments” and uncovered Chauvin’s left knee was on Floyd’s neck for the majority of the time. The combination of Floyd being handcuffed guiding his again, the officers’ manipulation of the cuffs, and the pavement beneath Floyd blended to interfere with Floyd’s means to breathe, Tobin testified.
The all round impact of the restraint was virtually “as if a surgeon experienced absent in and eradicated the lung,” he mentioned, referring to Floyd’s left lung. “A healthful individual subjected to what Mr. Floyd was subjected to would have died as a final result of what he was subjected to,” Tobin stated.
