First, jurors in the upcoming trial will be instructed not to consider Chauvin's guilty verdicts, but they will likely be aware of them because of the trial's publicity. Chauvin's conviction is also important in that an acquittal would have been "disastrous" for the prosecution's case against the three other officers, in terms of appearances and public opinion, according to CNN senior legal analyst Elie Honig.

Prosecutors could have a similar incentive, too. Aiding and abetting charges are, by definition, one step removed from Chauvin's actions, which makes this a "substantially more difficult case" for the prosecution, Honig said.

"If I'm looking at this pragmatically as a prosecutor, I have to acknowledge this is a tougher case," Honig said.

The upcoming trial will be largely similar to Chauvin's, likely featuring many of the same bystander witnesses, use-of-force experts and medical experts. But because there are three defendants each making their own arguments, the trial will likely be longer and more convoluted than Chauvin's, Honig explained.

The officers' roles in Floyd's death

The three ex-officers' actions on May 25, 2020, were shown in detail during Chauvin's trial in videos from bystanders, police body cameras and surveillance footage.

Lane and Kueng were the first responding officers on scene when the Cup Foods store called police about a man using a suspected fake $20 bill. The two officers then went to a vehicle with Floyd sitting in the driver's seat. Lane pulled out his firearm and pointed it at Floyd, yelling at the 46-year-old Black man to show his hands, according to their body camera footage.

Lane pulled Floyd from the vehicle and handcuffed him, and after a conversation on the sidewalk, the officers moved to put Floyd in the back of their squad car. Floyd resisted going inside the cramped vehicle, saying he was claustrophobic, and the officers physically struggled with him and tried to force him inside, the videos show.

Chauvin and Thao arrived in a separate squad car and tried to assist in getting Floyd into the vehicle. Chauvin then pulled Floyd from the vehicle and placed him on his stomach on the street, the videos show. He put his knees on Floyd's neck and back, while Kueng held down Floyd's torso and Lane held his legs.

While Chauvin, Kueng and Lane restrained Floyd, Thao stood nearby and blocked concerned bystanders from getting close, repeatedly raising his voice and arguing with them.

During the restraint, Lane is heard asking, "should we roll him on his side?" and Chauvin responded, "No, staying put where we got him," according to body camera videos. Minutes later, Lane again said, "want to roll him on his side?" the videos show. Kueng checked for Floyd's pulse but could not find one. The officers at no point moved Floyd into a side recovery position to help with his breathing.

The officers' backgrounds

Both Kueng and Lane were rookie officers without much experience.

Kueng was hired as a police officer with the Minneapolis Police Department in December 2019. He had joined the department as a cadet in February 2019. He had no prior complaints. When Floyd's death took place, it was Kueng's third shift as a police officer, his attorney Thomas Plunkett said last year. Chauvin was Kueng's training officer, according to Plunkett.

Lane also joined the police department as a cadet in February 2019. He didn't have a history of complaints. He had been on the police force for four days when Floyd died, his attorney Earl Gray said last year. Lane was "doing everything he thought he was supposed to do as a four-day police officer," Gray said.

Thao had been a police officer with the Minneapolis Police Department since 2012. He had six complaints filed with internal affairs, one of which was still open, according to a Minneapolis Police Department internal affairs public summary. The other five were closed without discipline.
