MINNEAPOLIS (AP) — Three former Minneapolis officers headed to a federal trial on civil rights charges this week in the death of George Floyd aren’t as familiar to most people as Derek Chauvin, a fellow officer who was convicted of murder last spring.

Thomas Lane and J. Kueng were the first officers to respond to a report that Floyd had tried to pass a counterfeit $20 bill, and they helped Chauvin restrain Floyd. Tou Thao, the second-most senior officer on the scene after Chauvin, held back a group of bystanders shouting at the officers to get off Floyd.

Lane and Kueng were rookies just a few days into their jobs as full-fledged officers. Though both took note of Floyd’s deteriorating condition — Kueng remarked that he couldn’t find a pulse, and Lane asked if they should flip Floyd onto his side — neither tried to stop Chauvin as he pressed his knee into the handcuffed Black man’s neck.

After the federal trial, Lane, Kueng and Thao face state charges of aiding and abetting murder.

Here’s a further look at the three former officers:

Tou Thao

Thao was Chauvin’s partner that day. Thao, a Hmong American, had been with the Minneapolis Police Department for around 11 years, starting as a community service officer, a program meant to foster diversity by grooming potential cops. He had been a full-fledged police officer for more than eight years.

Thao joined the force part time in 2008 while attending North Hennepin Community College. He was laid off temporarily at the end of 2009 during a budget crunch. He also previously worked as a security guard at Boston Scientific facilities in the Minneapolis area, as a supermarket stocker and as a trainer at a McDonald’s.

City records show six complaints were filed against Thao. He was also the subject of a 2017 federal lawsuit accusing him and another officer of excessive force. According to the lawsuit, Lamar Ferguson claimed that in 2014, Thao and his partner stopped him and beat him while Ferguson was on his way to his girlfriend’s house. The lawsuit was settled for $25,000.

Thao’s attorney is Robert Paule.

Thomas Lane

Lane, who is white, joined the department in early 2019 as a 35-year-old cadet — much older than most rookies. He had no complaints in his file during his short time on the force.

According to the Star Tribune, he followed three generations of men from his mother’s family into the Minneapolis Police Department, including his great-great-grandfather Michael Mealey, who was chief from 1911 to 1912.

His previous jobs included stints as a corrections officer at Hennepin County’s juvenile jail and as an assistant probation officer with a Ramsey County residential program for juvenile offenders. The University of Minnesota graduate also said on his employment forms that he had done volunteer work tutoring Somali youth and at-risk elementary school students, and with a police activities league for kids on Minneapolis’ predominantly Black north side.

Lane’s attorney is Earl Gray, who represented former Brooklyn Center officer Kim Potter, who was convicted of manslaughter in December in the shooting death of Daunte Wright. Gray also was on the defense team that won an acquittal in 2017 for former St. Anthony Officer Jeronimo Yanez in the shooting death of Philando Castile.

J. Kueng

Kueng, who is Black, was the youngest of the four officers at the scene. He was partnered with Lane that day. He was raised by his mother in north Minneapolis.

Family members told The New York Times in 2020 that Kueng, the son of a white mother and Nigerian father, wanted to become a police officer to bridge the gap between police and the Black community. Two of his siblings have spoken out critically about his role in Floyd’s death.

His personnel file, which says he speaks, reads and writes Russian, did not list any disciplinary actions.

Kueng was a 2018 graduate of the University of Minnesota, where he worked part-time in campus security. Like Thao, he was also a community service officer. He also worked nearly three years as a theft-prevention officer at the former Macy’s in downtown Minneapolis. And he worked short stints as a stocker at the downtown Target store, and as a youth baseball and soccer coach in Brooklyn Center.

Kueng and family members traveled to Haiti to volunteer after the 2010 earthquake, according to relatives and his attorney.

Kueng’s attorney is Tom Plunkett, who helped represent former Minneapolis Officer Mohamed Noor in the 2017 shooting death of Justine Ruszczyk Damond. Noor’s conviction for third-degree murder was overturned, but his manslaughter conviction stands.
