Tou Thao was concerned about the crowd gathering as three officers were restraining George Floyd.
As Thomas Lane was talking with Floyd after he responded to a call about someone using a counterfeit $20 bill, Lane pulled his gun. He later held Floyd down by his legs.
J. Alexander Kueng couldn't find a pulse for Floyd while Derek Chauvin had his knee pressed into Floyd's neck. Still, Kueng held Floyd down by his back.
And Chauvin kept his knee pressed to Floyd's neck for nearly nine minutes, which, according to a county medical examiner, led to Floyd's death. Criminal complaints filed Wednesday against all four now-fired police officers detail the moments leading up to Floyd's death, which has been ruled a homicide and sparked outrage and protests worldwide.
Chauvin, who was arrested last week, has been charged with second-degree murder and manslaughter. The second-degree murder charge was announced Wednesday by Minnesota Attorney General Keith Ellison, who also announced aiding and abetting charges against the other three former Minneapolis officers.
Thao, Lane and Kueng were all in custody in the Hennepin County Jail on $1 million bail, according to the jail's online roster search. Kueng has a court appearance set for Friday.
According to the criminal complaints filed against the officers, Lane and Kueng were the first officers on the scene after someone called 911 to report Floyd purchasing merchandise from Cup Foods with allegedly fake money. Both Kueng and Lane had their body-worn cameras running.
The two officers found Floyd in a car around the corner from the store with two other people. Lane began speaking to him while Floyd was still in the driver's seat, according to court documents. Lane pulled his gun while talking with Floyd and directed him to show his hands. Floyd complied and Lane holstered his gun.
While Kueng was speaking to the passengers, Lane told Floyd to get out of the car and handcuffed him. Floyd sat down and was "calm," according to the complaint, and Lane explained to Floyd that he was under arrest "for passing counterfeit currency." Lane also asked Floyd if he was "on anything."
Lane and Kueng tried to put Floyd into their squad car, and "Mr. Floyd stiffened up and fell to the ground," Lane's complaint states. According to documents, Floyd told officers "he was not resisting but did not want to get in the back seat and was claustrophobic."
Soon, Chauvin and Thao arrived at the scene. The officers attempted to get Floyd into a patrol car, while Floyd said he couldn't breathe. Chauvin and Kueng tried to get Floyd into the car from the passenger seat while the other officers tried pushing him from the driver's side, according to court documents.
When that didn't work, Chauvin pulled Floyd out of the passenger side of the car and Floyd "went to the ground face down and still handcuffed," the complaint said. Kueng held Floyd's back and Lane held his legs while Chauvin put his left knee on Floyd's neck, court documents state.
Floyd repeatedly said he couldn't breathe. At one point he said, "I'm about to die."
The officers kept their positions.
Thao got a hobble restraint but the other officers "decided not to use it and maintained their positions," Thao's complaint says.
After Thao looked at how the officers were restraining Floyd, "The defendant then became concerned about a number of citizens who had gathered and were watching the officers subdue Mr. Floyd, and potential traffic concerns, and so the defendant stood between those citizens and the three officers," Thao's criminal complaint states.
"When one citizen stepped off the curb, imploring Chauvin to get off of Mr. Floyd, the defendant put his hands on the citizen to keep him back."
After that, one of the officers said Floyd was "talking fine." Lane asked if Floyd should be flipped on his side and said, "I am worried about excited delirium or whatever." Chauvin said, "That's why we have him on his stomach."
"Despite his comments, the defendant took no actions to assist Mr. Floyd, to change his position, or to reduce the force the officers were using against Mr. Floyd," Lane's complaint states.
Kueng checked Floyd's wrist for a pulse and said, "I couldn't find one," while Chauvin's knee was still pressed into Floyd's neck, Kueng's complaint states. Chauvin didn't remove his knee from Floyd's neck for about two minutes after Floyd appeared to stop breathing, according to court documents.
An independent autopsy commissioned by Floyd's family and the Hennepin County Medical Examiner both ruled Floyd's death a homicide. The report from the medical examiner stated Floyd's cause of death as "cardiopulmonary arrest complicating law enforcement subdual, restraint and neck compression."
The examiner also reported Floyd "died from cardiopulmonary arrest while being restrained by law enforcement officers," according to court documents. Toxicology testing "revealed the presence of fentanyl and evidence of recent methamphetamine use."
"The ME opined that the effects of the officers' restraint of Mr. Floyd, his underlying health conditions, and the presence of the drugs contributed to his death," court documents state.
