Derek Chauvin used force against arrestees 6 other times. The jury in the George Floyd case won't hear about them.

  Derek Chauvin used force against arrestees 6 other times. The jury in the George Floyd case won't hear about them. Prosecutors tried to introduce six incidents in which they say Derek Chauvin used unreasonable force on people. The judge didn't allow them.The jury considering murder and manslaughter charges against Chauvin won't hear about any of them. And their verdict may be influenced as much by what they don't know as what they do.

A pulmonary expert testifying in the trial of Derek Chauvin on Thursday said Chauvin kept his knee on George Floyd's neck for more than three minutes after there was not "one ounce of oxygen left in the body."

Prosecutor Jerry Blackwell presented a graphic illustrating the moment Floyd's oxygen level reached zero. When Blackwell asked if Chauvin had lifted his knee from Floyd's neck at that point, pulmonologist Martin Tobin said he did not.

"The knee remained on the neck for another three minutes and two seconds after we reach the point where there is not one ounce of oxygen left in the body," Tobin told Blackwell.

Defense set to take turn in ex-cop's trial in Floyd death

  Defense set to take turn in ex-cop's trial in Floyd death MINNEAPOLIS (AP) — The defense for a former Minneapolis police officer charged in George Floyd's death was set to start presenting its case Tuesday, following 11 days of a prosecution narrative that combined wrenching video with clinical analysis by medical and use-of-force experts to condemn Derek Chauvin's actions. Prosecutors called their final witnesses Monday, leaving only some administrative matters before they were expected to rest Tuesday. Once the defense takes over, Chauvin attorney Eric Nelson is expected to have his own experts testify that it was Floyd's drug use and bad heart, not Chauvin's actions, that killed him.

Tobin said he determined the moment there was no oxygen left in Floyd's body by using "very precise science."

"You can figure this out with very precise science, looking at once somebody stops breathing, what will be the rate of decline in the level of oxygen, how long it will take to reach zero ... so we see here that he reaches a level of zero of oxygen," Tobin said, when explaining how the moment was determined.

Later in his testimony, Tobin, after recognizing the pre-existing health conditions Floyd had, said that a "healthy person" subjected to the same circumstances as Floyd would have died as well.

"Now Dr. Tobin, are you aware that Mr. Floyd had some pre-existing health conditions?" Blackwell asked.

"Yes, I am," Tobin responded, adding, when prompted by Blackwell, that he read them in the records from Hennepin County and saw them mentioned in the autopsy report.

Duty sergeant: Officers could have ended Floyd restraint

  Duty sergeant: Officers could have ended Floyd restraint MINNEAPOLIS (AP) — A Minneapolis police supervisory sergeant who was on duty the night George Floyd died testified that he believes the officers who restrained Floyd could have ended it after he stopped resisting. David Pleoger testified Thursday at the trial of since-fired officer Derek Chauvin, who is charged with murder and manslaughter in Floyd's death. He noted that officers are trained to roll people on their side to help with their breathing after they have been restrained in the prone position.

"Do you have an opinion to a reasonable degree of medical certainty as to whether a person who had none of those pre-existing health conditions, a healthy person, would have died of the same circumstances as Mr. Floyd?" Blackwell asked.

"Yes, a healthy person subjected to what Mr. Floyd was subjected to would have died as a result of what he was subjected to," Tobin answered.

Virtually all of the jurors took notes after Tobin said Chauvin kept his knee on Floyd's neck after he determined there was no more oxygen in Floyd's body, according to a pool report.

Tobin is the first witness to take the stand on day eight in the trial of Chauvin, the former Minneapolis police officer who was charged with three criminal counts in connection to Floyd's death.

Chauvin was caught on video footage in May with his knee on Floyd's neck for approximately nine minutes during an arrest.

Day 9 of Chauvin trial: Expert witness Tobin says Chauvin's knee cut off Floyd's air .
Testimony from pulmonologist Martin Tobin dominated the ninth day of former Minneapolis Police officer Derek Chauvin's trial, as the doctor provided jurors comment about George Floyd's ability to breathe while under restraint. During his time at the stand, Tobin refuted the impact fentanyl had on Floyd's breathing just before he lost consciousness, and pushed back against claims that preexisting health conditions caused his death.
