The court is taking a break for lunch until 1:30 Central Time after more than two hours of testimony from a lung doctor. After the break, Derek Chauvin’s lawyer will have a chance to cross-examine the doctor.

A veteran lung doctor testified on Thursday that George Floyd’s death was caused in part by Derek Chauvin’s knees pressing against his neck and back, making it impossible for him to breathe, and that Mr. Floyd showed signs of a brain injury about four minutes before Mr. Chauvin lifted his knee from his neck.

Dr. Martin J. Tobin, a pulmonologist and critical care doctor in Chicago, said in court that the combination of Mr. Chauvin’s pressure, the handcuffs pulling Mr. Floyd’s hands behind his back and Mr. Floyd’s body being pressed against the street had caused him to die “from a low level of oxygen.”

The testimony from Dr. Tobin on the ninth day of the trial of Mr. Chauvin, the former Minneapolis police officer who has been charged with murdering Mr. Floyd, signaled a shift into a new phase in which medical testimony will be crucial. Mr. Chauvin’s lawyer has suggested that Mr. Floyd died from the fentanyl and methamphetamine that were found in his system, but prosecutors argue that Mr. Chauvin had killed him by kneeling on him for more than nine minutes and cutting off his air supply.

Dr. Tobin was adamant that Mr. Chauvin’s actions had caused Mr. Floyd’s death on May 25. He pinpointed the exact moment, in the graphic bystander video of the arrest, in which he said Mr. Floyd had died, noting that his eyes had opened wide and then closed again. At that point, Mr. Chauvin’s knee remained on his neck.

“You can see his eyes — he’s conscious — and then you see that he isn’t,” Dr. Tobin said. “That’s the moment the life goes out of his body.”

The doctor also rejected the defense’s arguments about drugs, saying that videos show Mr. Floyd breathing at a normal rate before he went unconscious, meaning any fentanyl in his system was “not having an effect” on his breathing.

“A healthy person subjected to what Mr. Floyd was subjected to would have died,” Dr. Tobin said.

After analyzing videos of the arrest, Dr. Tobin said he determined that Mr. Chauvin had pressed his left knee on Mr. Floyd’s neck for more than 90 percent of the time that Mr. Floyd was on the ground, and that he had kept his right knee on Mr. Floyd’s back for the majority of the time as well. That pressure, combined with having his hands cuffed behind his back and pushed into the street facedown, had cut off oxygen and caused his heart to stop, Dr. Tobin said.

“He was being squashed between the two sides,” he said.

Mr. Floyd was so desperate for air at one point that he tried to lift himself off the ground by pushing his right knuckle against a police car’s tire, the doctor said.

Dr. Tobin, who works in pulmonology and critical care at Edward Hines Jr. Veterans Affairs Hospital and at Loyola University’s medical school, spoke for more than two hours to jurors. He said he had asked not to be paid when prosecutors asked if he would testify in the case. At several points, he encouraged jurors to feel parts of their own necks to demonstrate what he was saying; most of them followed along.

Dr. Tobin said the factors that cut off Mr. Floyd’s air supply had led to “asphyxia,” which he said is just another word for oxygen deprivation; a prosecutor told jurors when the trial began that Mr. Floyd had died of asphyxia.

At one point in a video of Mr. Floyd’s arrest, Dr. Tobin noted, Mr. Chauvin’s left foot appeared to rise off the ground, which the doctor said meant that half of Mr. Chauvin’s body weight was pressing on Mr. Floyd’s neck.

After about 4 minutes and 51 seconds, Dr. Tobin said, Mr. Floyd stopped speaking or groaning. After just over 5 minutes, Mr. Floyd appeared to straighten out his legs, which Dr. Tobin said was a signal that Mr. Floyd was having a type of seizure because he had suffered a brain injury from the oxygen deprivation. He said Mr. Chauvin’s knee had stayed on Mr. Floyd’s neck for 3 minutes and 27 seconds after he took his last breath.

The doctor said the handcuffs were also an “extremely important” factor in Mr. Floyd’s death because Mr. Chauvin and another officer had pushed his hands upward and against his back, pressing his chest against the hard street.

“When you’re turned prone and with the knee on the back, now the work that Mr. Floyd has to perform becomes huge,” Dr. Tobin said, adding: “He has to try to lift up the officer’s knee with each breath.”

A lot of big words here, but an important point by Dr. Martin J. Tobin about George Floyd’s breathing. He essentially said that Floyd’s breathing did not slow down enough to say that fentanyl was a factor in his not getting enough oxygen. In other words, he was breathing at a normal rate before he became unconscious. The defense has argued that fentanyl was a cause of Floyd’s inability to breathe.

Dr. Martin J. Tobin also says the increased level of carbon dioxide in George Floyd’s body was not because of fentanyl, but because he wasn’t given any ventilation for nearly 10 minutes.

One thing that Dr. Martin J. Tobin is doing quite effectively is clarifying that multiple terms — hypoxia, asphyxia, anoxia — all mean essentially the same thing. He’s saying the jury doesn’t need to worry about the medical terminology because the words all refer to a “drastically low level of oxygen.”

The defense has argued that George Floyd died because of his poor health and because he had drugs in his system. Dr. Martin J.

One really effective thing that the prosecution is accomplishing with Dr. Martin J. Tobin: They’re making it irrelevant whether Derek Chauvin’s knee was actually on George Floyd’s neck versus his back or shoulders. It’s all bad for his breathing is the main takeaway. That might be a reason why prosecutors are going with asphyxia (oxygen deficiency) as the cause of death, rather than what the medical examiner determined, “cardiopulmonary arrest,” which means the heart stops.

Dr. Martin J. Tobin is now getting into some complicated terminology about oxygen reserves, but it all points to a general theme: George Floyd being in a prone position, handcuffed with a knee in his neck, led to a reduction in his oxygen reserves.

This is an analysis of inches. Dr. Martin J. Tobin points to a photo in which Derek Chauvin’s toe is slightly off the pavement as he kneels on George Floyd’s neck. “This means that all of his body weight is being directed down at Mr. Floyd’s neck,” Tobin said.

Dr. Martin J. Tobin, a renowned expert on breathing, was a key witness for the prosecution on Thursday, agreeing to testify without pay to offer his opinion on what caused George Floyd’s death:

Mr. Floyd died from a low level of oxygen and this caused damage to his brain that we see and it also caused a P.E.A. arrhythmia that caused his heart to stop.

The testimony was an attempt to discredit defense arguments that Mr. Floyd’s drug use contributed to his death. Using video from the arrest, Dr. Tobin described how Derek Chauvin’s knees on Mr. Floyd’s neck and side and his hold on Mr. Floyd’s arms prevented Mr. Floyd from being able to breathe.

He’s jammed down against the street, and so the street is playing a major role in preventing him from expanding his chest.

He also showed two photos of Mr. Floyd’s finger and knuckles digging into the street and the police car’s tire as the police held him down:

To most people this doesn’t look terribly significant. But to a physiologist this is extraordinarily significant because this tells you that he has used up his resources and he is now literally trying to breathe with his fingers and knuckles.

Dr. Tobin said people who can’t breathe normally will use other ways to try to bring more air into their body:

So he’s using his fingers and his knuckles against the street to try to crank up the right side of his chest. This is his only way to try to and get air into the right lung.

Dr. Martin J. Tobin, a pulmonologist and critical care physician from the Chicago area, was the first witness prosecutors called to the stand in the Derek Chauvin trial on Thursday.

When prosecutors asked if he had formed a medical opinion on what had caused George Floyd’s death, Dr. Tobin said, “Mr. Floyd died from a low level of oxygen, and this caused damage to his brain that we see, and it also caused a P.E.A. arrhythmia because his heart stopped,” referring to pulseless electrical activity, or cardiac arrest.

The low level of oxygen was caused by “shallow breathing,” he said. Mr. Floyd’s prone position and being handcuffed and Mr. Chauvin’s knee on his neck and back, he said, contributed to the shallow breathing.

Dr. Tobin added that the position in which Mr. Floyd was handcuffed, with the force of the officers compounding with the asphalt street, ultimately prevented him from being able to breathe fully.

“It’s how the handcuffs are being held, how they’re being pushed, where they’re being pushed that totally interfere with central features of how we breathe,” he said.

Mr. Chauvin’s knee placed on the left side of his chest would have limited the amount of air being able to enter the left lung, Dr. Tobin said, as if “a surgeon had gone in and removed the lung,” he said.

Dr. Tobin attended medical school at University College Dublin and is an expert in acute respiratory failure, mechanical ventilation and neuromuscular control of breathing.

He is certified by the American Board of Internal Medicine and the American Board of Internal Medicine Subspecialty Pulmonary Disease.

And you’ll see Mr. Floyd doing his best to kind of crank his right shoulder, having to lift up his weight and Mr. Chauvin’s weight on top of him to get a breath.”

In Minneapolis, educators have grappled over the last few weeks with how to talk with their students about the trial of Derek Chauvin, the former Minneapolis police officer charged with murder in George Floyd’s death.

Some teachers have shown segments of the televised trial in class and used jury selection or witness testimony as an opportunity to explore the complex issues of race, policing and the criminal justice system. Others have cautiously given students the chance to ask questions and share their opinions. And school administrators and counselors have scheduled talking circles, where children can open up about how the trial has rekindled feelings of racial trauma and fears of potential unrest stirred by the sound of helicopters flying over the city.

But the adult nature of the televised murder trial, marked by graphic videos and emotional eyewitness accounts, poses a challenge for educators, even as they say the court proceedings are too important to ignore.

“We have to engage even if we’re uncomfortable and we don’t have the answers,” said Kristi Ward, the principal for third through eighth graders at Lake Nokomis Community School in south Minneapolis.

The trial of Derek Chauvin will continue on Thursday with a renewed focus on George Floyd’s drug use, after a day of testimony that suggested Mr. Floyd had drugs with him when he was arrested in Minneapolis last May.

Mr. Floyd’s drug use has been a primary focus of the defense of Mr. Chauvin, the former police officer who is charged with murdering Mr. Floyd.

On Wednesday, witnesses described the Minnesota Bureau of Criminal Apprehension’s investigation into Mr. Floyd’s death, explaining that pills and pill fragments found at the scene contained methamphetamine and fentanyl. The defense, led by the lawyer Eric J. Nelson, has suggested that Mr. Floyd died from complications of drug use.

The jury also heard from a use-of-force expert who said Mr. Chauvin used “deadly force” even though Mr. Floyd posed no immediate threat to the officers. “He was in the prone position, he was handcuffed, he was not attempting to resist, he was not attempting to assault the officers — kick, punch, or anything of that nature,” said the expert, Sgt. Jody Stiger, who works with the Inspector General’s Office for the Los Angeles Police Department.

Sergeant Stiger said that Mr. Chauvin may have been justified if he had decided to use a Taser earlier in the arrest, when Mr. Floyd resisted as officers tried to put him in the back of a police cruiser. But once Mr. Floyd was handcuffed and face down on the street, the force should have stopped, the sergeant said. Mr. Chauvin kept his knee on Mr. Floyd for more than nine minutes.

The sergeant added that being in a prone position while handcuffed can make it difficult to breathe, saying, “When you add body weight to that, it just increases the possibility of death.”

The latter half of Wednesday’s testimony, which focused on the Minnesota Bureau of Criminal Apprehension’s investigation, seemed to indicate a shift away from questions about whether Mr. Chauvin violated police policy and toward the issue of drugs.

More than 20 witnesses have taken the stand for the prosecution, but the defense has to then call its witnesses, after which the trial can move into closing arguments. A verdict may still be weeks away.

A use-of-force expert called by prosecutors testified on Wednesday that Derek Chauvin, the police officer charged with murdering George Floyd, used “deadly force” when it was appropriate to use none.

The expert, Sgt. Jody Stiger, who works with the Los Angeles Police Department Inspector General’s Office, also said that Mr. Chauvin put Mr. Floyd at risk of positional asphyxia, or a deprivation of oxygen. His testimony could corroborate one of the prosecution’s primary assertions: That Mr. Floyd died from asphyxia because Mr. Chauvin knelt on him for more than nine minutes.

Senior Special Agent James D. Reyerson of the Minnesota Bureau of Criminal Apprehension, whose agency investigates police use of force, told jurors about the bureau’s investigation into Mr. Floyd’s death, and said that Mr. Floyd shouted “I ain’t do no drugs,” while he was handcuffed. Here are the highlights from Wednesday.

  • Sergeant Stiger testified that “no force should have been used” once Mr. Floyd was subdued, handcuffed and facedown on the pavement. “He was in the prone position, he was handcuffed, he was not attempting to resist, he was not attempting to assault the officers — kick, punch, or anything of that nature,” Sergeant Stiger said. The prosecution has argued that Mr. Chauvin’s force continued for far longer than necessary; in all, Mr. Chauvin pinned Mr. Floyd with his knee for about nine and a half minutes.

  • Responding to questions from the defense, Sergeant Stiger said that Mr. Floyd resisted arrest when the responding officers tried to put him in the back of a squad car. In that moment, Mr. Chauvin would have been justified in using a Taser, Sergeant Stiger said. The defense has suggested that people who do not appear to be dangerous to officers can quickly pose a threat. The line of questioning appeared to be an attempt to establish that Mr. Floyd had been combative at first, and therefore could have become so once again. Sergeant Stiger pushed back on the argument, saying that officers should use force that is necessary for what suspects are doing in the moment, not what they might do later.

  • Asked to interpret footage from a police body camera, Mr. Reyerson initially said Mr. Floyd appeared to say, “I ate too many drugs.” But in later testimony, Mr Reyerson changed his assessment and said that Mr. Floyd had actually shouted, “I ain’t do no drugs.” His revised judgment could chip away at Mr. Chauvin’s defense, which has tried to argue that Mr. Floyd died from complications of drug use, not the actions of Mr. Chauvin. A toxicology report found methamphetamine and fentanyl in Mr. Floyd’s system. Sergeant Stiger told the jury that he could not make out what Mr. Floyd said in that moment.

  • Much of Wednesday’s proceedings focused on Mr. Floyd’s drug use. The jury heard testimony from McKenzie Anderson, a forensic scientist with the Minnesota Bureau of Criminal Apprehension who processed the squad car that Mr. Floyd was briefly placed in on the night he died. An initial processing found no drugs in the vehicle, but during a second search requested by Mr. Chauvin’s defense team in January, the team discovered fragments of pills. Judge Peter Cahill has called the oversight “mind-boggling.” Ms. Anderson said she was not looking for pills during the initial search, and simply passed over them. In testing the fragments, Ms. Anderson said a lab found D.N.A. that matched Mr. Floyd’s.

  • Breahna Giles, a forensic scientist with the Minnesota Bureau of Criminal Apprehension, testified that some of the pills recovered at the scene were tested and found to contain methamphetamine and fentanyl. The pills were marked with letters and numbers that seemed to indicate that they were pharmaceutical-grade Acetaminophen and Oxycodone, though illicit pills are sometimes marked by drug dealers to give the false impression that they came from a pharmacy.

Midway through the second week of the trial of Derek Chauvin, more than 20 witnesses have already taken the stand for the state. Next, the defense will present their witnesses, before the trial moves into closing arguments and, finally, jury deliberation.

Witness testimony is expected to last at least through the end of next week. On Friday, Judge Peter A. Cahill dismissed court early, saying that the trial was ahead of schedule.

Jury selection — eight days of intense questioning to potential jurors about their political biases and views on racism and policing — began on March 9. Ultimately, 12 jury members and two alternates were chosen.

Both sides delivered opening statements on March 29, which were followed by the prosecution calling their witnesses to the stand. Each witness is questioned by the state, then cross-examined by the defense. Questioning goes back and forth between the state and the defense.

Each side submitted a list of potential witnesses to the judge ahead of the trial: The state submitted the names of 363 potential witnesses, and the defense listed 212, but it’s unclear how many will actually appear.

Closing arguments could come as soon as the week after next, then the jury will begin deliberating. The jury can take as long as it needs to deliver a verdict.

How George Floyd Was Killed in Police Custody

The Times has reconstructed the death of George Floyd on May 25. Security footage, witness videos and official documents show how a series of actions by officers turned fatal. (This video contains scenes of graphic violence.)

It’s a Monday evening in Minneapolis. Police respond to a call about a man who allegedly used a counterfeit $20 bill to buy cigarettes. Seventeen minutes later, the man they are there to investigate lies motionless on the ground, and is pronounced dead shortly after. The man was 46-year-old George Floyd, a bouncer originally from Houston who had lost his job at a restaurant when the coronavirus pandemic hit. Crowd: “No justice, no peace.” Floyd’s death triggered major protests in Minneapolis, and sparked rage across the country. One of the officers involved, Derek Chauvin, has been arrested and charged with second-degree murder. The other three officers have been charged with aiding and abetting murder. The Times analyzed bystander videos, security camera footage and police scanner audio, spoke to witnesses and experts, and reviewed documents released by the authorities to build as comprehensive a picture as possible and better understand how George Floyd died in police custody. The events of May 25 begin here. Floyd is sitting in the driver’s seat of this blue S.U.V. Across the street is a convenience store called Cup Foods. Footage from this restaurant security camera helps us understand what happens next. Note that the timestamp on the camera is 24 minutes fast. At 7:57 p.m., two employees from Cup Foods confront Floyd and his companions about an alleged counterfeit bill he just used in their store to buy cigarettes. They demand the cigarettes back but walk away empty-handed. Four minutes later, they call the police. According to the 911 transcript, an employee says that Floyd used fake bills to buy cigarettes, and that he is “awfully drunk” and “not in control of himself.” Soon, the first police vehicle arrives on the scene. Officers Thomas Lane and J. Alexander Kueng step out of the car and approach the blue S.U.V. Seconds later, Lane pulls his gun. We don’t know exactly why. He orders Floyd to put his hands on the wheel. Lane reholsters the gun, and after about 90 seconds of back and forth, yanks Floyd out of the S.U.V. A man is filming the confrontation from a car parked behind them. The officers cuff Floyd’s hands behind his back. And Kueng walks him to the restaurant wall. “All right, what’s your name?” From the 911 transcript and the footage, we now know three important facts: First, that the police believed they were responding to a man who was drunk and out of control. But second, even though the police were expecting this situation, we can see that Floyd has not acted violently. And third, that he seems to already be in distress. Six minutes into the arrest, the two officers move Floyd back to their vehicle. As the officers approach their car, we can see Floyd fall to the ground. According to the criminal complaints filed against the officers, Floyd says he is claustrophobic and refuses to enter the police car. During the struggle, Floyd appears to turn his head to address the officers multiple times. According to the complaints, he tells them he can’t breathe. Nine minutes into the arrest, the third and final police car arrives on the scene. It’s carrying officers Tou Thao and Derek Chauvin. Both have previous records of complaints brought against them. Thao was once sued for throwing a man to the ground and hitting him. Chauvin has been involved in three police shootings, one of them fatal. Chauvin becomes involved in the struggle to get Floyd into the car. Security camera footage from Cup Foods shows Kueng struggling with Floyd in the backseat while Thao watches. Chauvin pulls him through the back seat and onto the street. We don’t know why. Floyd is now lying on the pavement, face down. That’s when two witnesses begin filming, almost simultaneously. The footage from the first witness shows us that all four officers are now gathered around Floyd. It’s the first moment when we can clearly see that Floyd is face down on the ground, with three officers applying pressure to his neck, torso and legs. At 8:20 p.m., we hear Floyd’s voice for the first time. The video stops when Lane appears to tell the person filming to walk away. “Get off to the sidewalk, please. One side or the other, please.” The officers radio a Code 2, a call for non-emergency medical assistance, reporting an injury to Floyd’s mouth. In the background, we can hear Floyd struggling. The call is quickly upgraded to a Code 3, a call for emergency medical assistance. By now another bystander, 17-year-old Darnella Frazier, is filming from a different angle. Her footage shows that despite calls for medical help, Chauvin keeps Floyd pinned down for another seven minutes. We can’t see whether Kueng and Lane are still applying pressure. Floyd: [gasping] Officer: “What do you want?” Bystander: “I’ve been —” Floyd: [gasping] In the two videos, Floyd can be heard telling officers that he can’t breathe at least 16 times in less than five minutes. Bystander: “You having fun?” But Chauvin never takes his knee off of Floyd, even as his eyes close and he appears to go unconscious. Bystander: “Bro.” According to medical and policing experts, these four police officers are committing a series of actions that violate policies, and in this case, turn fatal. They’ve kept Floyd lying face down, applying pressure for at least five minutes. This combined action is likely compressing his chest and making it impossible to breathe. Chauvin is pushing his knee into Floyd’s neck, a move banned by most police departments. Minneapolis Police Department policy states an officer can only do this if someone is, quote, “actively resisting.” And even though the officers call for medical assistance, they take no action to treat Floyd on their own while waiting for the ambulance to arrive. Officer: “Get back on the sidewalk.” According to the complaints against the officers, Lane asks him twice if they should roll Floyd onto his side. Chauvin says no. Twenty minutes into the arrest, an ambulance arrives on the scene. Bystander: “Get off of his neck!” Bystander: “He’s still on him?” The E.M.T.s check Floyd’s pulse. Bystander: “Are you serious?” Chauvin keeps his knee on Floyd’s neck for almost another whole minute, even though Floyd appears completely unresponsive. He only gets off once the E.M.T.s tell him to. Chauvin kept his knee on Floyd’s neck for over eight minutes, according to our review of the video evidence. Floyd is loaded into the ambulance. The ambulance leaves the scene, possibly because a crowd is forming. But the E.M.T.s call for additional medical help from the fire department. But when the engine arrives, the officers give them, quote, “no clear info on Floyd or his whereabouts,” according to a fire department incident report. This delays their ability to help the paramedics. Meanwhile, Floyd is going into cardiac arrest. It takes the engine five minutes to reach Floyd in the ambulance. He’s pronounced dead at a nearby hospital around 9:25 p.m. Preliminary autopsies conducted by the state and Floyd’s family both ruled his death a homicide. The widely circulated arrest videos don’t paint the entire picture of what happened to George Floyd. Crowd: “Floyd! Floyd!” Additional video and audio from the body cameras of the key officers would reveal more about why the struggle began and how it escalated. The city quickly fired all four officers. And Chauvin has been charged with second degree murder. Thomas Lane, J. Alexander Kueng and Tou Thao were charged with aiding and abetting murder. But outrage over George Floyd’s death has only spread further and further across the United States.

On May 25, Minneapolis police officers arrested George Floyd, a 46-year-old Black man, after a convenience store employee called 911 to report that Mr. Floyd had bought cigarettes with a counterfeit $20 bill. Seventeen minutes after the first squad car arrived at the scene, Mr. Floyd was unconscious and pinned beneath three police officers, showing no signs of life.

By combining videos from bystanders and security cameras, reviewing official documents and consulting experts, The New York Times reconstructed in detail the minutes leading to Mr. Floyd’s death. Our video shows officers taking a series of actions that violated the policies of the Minneapolis Police Department and turned fatal, leaving Mr. Floyd unable to breathe, even as he and onlookers called out for help.

The trial of Derek Chauvin in the death of George Floyd is unusual for many reasons: It is being livestreamed from Minneapolis, attendance is severely limited because of the coronavirus and the public’s interest in the case may make this one of the highest-profile trials in recent memory.

The trial can be watched on nytimes.com, via a livestream provided by Court TV, which is also airing the trial in full. Witness testimony and lawyers’ presentations of evidence should last several weeks before the jury begins to deliberate over the verdict.

Among the people allowed in the courtroom, on the 18th floor of the Hennepin County Government Center, are: the judge, jurors, witnesses, court staff, lawyers, Mr. Chauvin and only a handful of spectators.

The judge, Peter A. Cahill, wrote in an order on March 1 that only one member of Mr. Floyd’s family and one member of Mr. Chauvin’s family would be allowed in the room at any time. Two seats are reserved for reporters, and various journalists, including from The New York Times, are rotating throughout the trial.

The lawyers, spectators, jurors and witnesses are required to wear masks when they are not speaking. Spectators are prohibited from having any visible images, logos, letters or numbers on their masks or clothing, according to Judge Cahill’s order.
