Lane and another rookie officer, J. Kueng, both held down Floyd as Chauvin pressed his knee against Floyd’s neck.
Kueng knelt on Floyd’s back and held Floyd’s handcuffed arms in place while Lane restrained Floyd’s legs with his hands and knees, according to the prosecution’s memorandum.
Another officer, Tou Thao, held back the crowd. All four officers were later fired.
The prosecution said Floyd told the officers at least 20 times in the first five minutes that he was on the ground that he could not breathe, and he told them nearly 10 times he was dying.
“And then he fell silent. He stopped moving. He stopped breathing. And the officers could not find a pulse,” according to the court document.
But Chauvin, Kueng and Lane continued to pin Floyd on the ground while Thao stood watch to prevent bystanders on the sidewalk from approaching, the memorandum said.
Lane continued to restrain Floyd’s legs for about three minutes after telling the other officers that Floyd was “passing out,” the memo said, and for a minute and a half after Kueng said Floyd did not have a pulse.
As Floyd lost consciousness, Lane asked the other officers if they should roll Floyd on his side. But Chauvin said an ambulance was coming.
“Lane did nothing to challenge Chauvin’s answer. Not one thing,” the prosecution said. Instead, Lane continued to hold down Floyd’s legs with his hands.
Lane joined emergency responders in the ambulance and began performing CPR on Floyd at the request of emergency personnel, but Floyd was pronounced dead at the hospital that evening.
Chauvin is charged with second-degree murder, third-degree murder and manslaughter. Lane, Kueng and Thao are charged with aiding and abetting both second-degree murder and manslaughter. Thao’s attorney also is arguing to dismiss the charges, saying his client only handled crowd control.
The next court hearing for the four is scheduled for September 11.
