Experts say Floyd died of lack of oxygen

Minneapolis (AP) —George Floyd died of oxygen deficiency as he held his hand behind him and was locked face down on the pavement, medical experts testified Thursday in a murder trial of former police officer Derek Chauvin. did.

Breathing while Floyd was being held down by Shobin and other officers was too shallow to take in enough oxygen, which damaged his brain and caused an abnormal heart rhythm that stopped the heart. Dr. Martin Tobin, who is critical of the lungs, said he is a care specialist at Edward Hines Junior VA Hospital in Chicago and Loyola University School of Medicine.

It was Shovin’s actions that killed a 46-year-old black man last May as part of the prosecutor’s efforts, noting Floyd’s illegal substance use and the underlying health conditions claimed by defense. Proved not.

Tobin said it took almost nine and a half minutes to analyze the graphic display of three police officers pinning what the prosecutor was saying about Floyd. Chauvin’s knee “was virtually on his neck most of the time,” he said. He said it was “more than 90% of the time in my calculations.”

He said Floyd was still talking, so he seemed to have had enough oxygen for the first five minutes to keep his brain alive.

However, Tobin explained to the jury what would happen if the airway space became narrower, saying that breathing would be “very difficult” and that it was worse than “breathing with a straw.”

Tobin testified that if the hypopharynx (lower part of the throat) was completely occluded, oxygen levels would drop to “either a seizure or a heart attack” in just a few seconds.

The prosecutor showed Floyd’s images side by side. One is the front of the face hitting the pavement and the other is the head facing. Tobin said that the ligaments behind his neck would have protected his airways when Floyd’s head was pointing down. But when I turned my head, Chauvin’s weight would have squeezed the hypopharynx.

Experts calculated that when Chauvin was in a nearly vertical position and his toes were off the ground, half of Chauvin’s weight (91.5 pounds) rested directly on Floyd’s neck.

Tobin said other factors exacerbated the impact on Floyd. He is J. Officer Quen held Floyd’s left hand upwards and pointed out that Chauvin’s right knee squeezed Floyd’s side. Handcuffs and a hard surface also interfered with Floyd’s ability to breathe, Tobin said.

Tobin used simple terms such as “pump handle” and “bucket handle” to describe the jury’s breathing behavior. At some point, he advised them to “examine your own neck, now all the jury,” to better understand the effects of knees on a person’s neck. Most of the juries felt their necks as Tobin directed, but the judge told them later that they didn’t have to.

Chauvin, 45, was charged with murder and manslaughter at Floyd’s death on May 25. Floyd was arrested outside a nearby market after being accused of trying to hand over a counterfeit $ 20 bill. When police tried to put him in a police car, Floyd, who sounded panicked, struggled and claimed to be claustrophobic, and they fixed him on the pavement.

A video of a bystander screaming that Floyd couldn’t breathe as he shouted to Chauvin caused protests and spread violence throughout the United States.

Attorney Eric Nelson claimed that the dismissed white police officer “did exactly what he had been trained in throughout his 19-year career,” claiming that Chauvin’s actions had killed Floyd. Fentanyl and methamphetamine were found in Floyd’s system.

Tobin’s testimony takes place the day after Chauvin testified that Chauvin had inflicted most of his nine-and-a-half-minute weight on Floyd’s neck or neck area and his entire back.

Jody Steiger, a sergeant at the Los Angeles Police Department and a witness to the prosecution, said Chauvin was on Floyd’s neck or neck area, and first aid after police began fixing Floyd to the ground, based on a review of video evidence. Make him a stretcher who said he put pressure on him until he started moving.

“Did that particular force change throughout the period of detention?” Prosecutor Steve Schleicher asked when he showed the jury a composite of five still images.

“Correct,” Steiger replied. Steiger testified on Tuesday that Chauvin used excessive force against Floyd.

Nelson countered by pointing out what he said was the moment in the video footage when Chauvin’s knees appeared to be in the area of ​​the scapula or at the base of the neck, rather than in Floyd’s neck.

Steiger agreed that his weight might have shifted from time to time, but gave less rationale, saying that some police officers’ knees in the disputed images still seem to be near Floyd’s neck. There wasn’t.

In another testimony on Tuesday, Minnesota investigator James Rayerson, the case’s chief investigator, initially said Floyd had “eaten too much medicine” in a police body camera video of his arrest. I agreed with Nelson.

But when the prosecutor played a longer clip of the video, Riason said he believed that what Floyd actually said was “I don’t take medicine.”
