You can see the exact moment “the light goes out” of George Floyd as ex-cop Derek Chauvin pressed a knee into his neck, a respiratory expert testified Thursday.
“You can see his eyes,” said Dr. Martin Tobin, who specializes in pulmonary and critical care medicine, at Chauvin’s murder trial in Hennepin County District Court as jurors were shown the disturbing clip.
“He’s conscious and then you see that he isn’t. That’s the moment the light goes out of his body.”
The footage shows Chauvin’s knee grinding the left side of Floyd’s face into the pavement — as Floyd’s eyes flicker ever so slightly before they go blank.
Just minutes earlier on May 25 of last year, Floyd, 46, had been arrested for passing a fake $20 bill at Cups Foods, a Minneapolis convenience store.
After resisting police officers’ attempts to get him in the back of a police cruiser, he was dragged to the ground, handcuffed behind his back, and positioned face-first against the pavement. Chauvin’s knees were pressed against Floyd’s neck and back for nine minutes and 29 seconds.
Alarmed bystanders begged Chauvin and the three other cops to relent as Floyd said “I can’t breathe” 27 times and called out for his mom.
Tobin said Thursday that even a healthier person couldn’t have survived the oxygen deprivation caused by the restrictive positioning.
The doctor described how Floyd would have felt like he was gasping for air through a straw as he slowly lost consciousness.
“He’s constantly cranking up the right side of his body, you can see there, to try and get some air into the right side of his chest, he’s making repeated struggling movements,” said Tobin, as prosecutors played the footage.
After about five minutes prone on the pavement, Floyd kicked out his leg in an extension then, seconds later, took his last breath
“You’re seeing here fatal injury to the brain from lack of oxygen,” said Tobin of the involuntary reaction.
Floyd was soon dead, but Chauvin’s knee remained on his neck for more than four minutes.
After studying the footage, Tobin concluded that Floyd died of oxygen deprivation caused by the way police had restrained him.
The defense has claimed that Floyd died of a drug overdose and a heart ailment.
Chauvin faces up to 40 years in prison if convicted of second-degree murder, third-degree murder and second-degree manslaughter.
Three other former Minneapolis police officers — Tou Thao, Thomas Lane and J. Alexander Kueng — are due to stand trial on charges of aiding and abetting murder and manslaughter in the case.
