Derek Chauvin worked for the Minneapolis Police Department for more than 18 years.
Throughout it all, protesters in Minneapolis and across the country demanded justice for Floyd and accountability for Chauvin.
Here’s what we know about the officer convicted on April 20 in Floyd’s murder.
He had 18 prior complaints against him
Before he knelt on Floyd’s neck, Chauvin was the subject of 18 prior complaints filed with the Minneapolis Police Department’s Internal Affairs.
Police confirmed the complaints were filed but didn’t detail why they were filed or what they entailed.
Only two of the 18 complaints were “closed with discipline,” according to a MPD internal affairs public summary. In both cases, Chauvin received a letter of reprimand.
According to Communities Against Police Brutality, a Minnesota nonprofit that created a database of complaints against officers in the state, Chauvin received oral reprimands for using a “demeaning tone,” “derogatory language” and other language that merited discipline.
Neither the nonprofit database nor the Minneapolis internal affairs public summary include dates or descriptions that incited the complaints.
Former officer Tou Thao, who was also involved in Floyd’s arrest, had six complaints filed with internal affairs, one of which was still open, the summary said. The other five were closed without discipline.
The other two former officers, J. Alexander Kueng and Thomas Lane, had no complaints filed, according to a MPD internal affairs public summary.
He and George Floyd once worked security shifts at the same nightclub
Both men worked security at the El Nuevo Rodeo club, down the street from Minneapolis’ Third Precinct, former club owner Maya Santamaria told CNN.
Floyd worked some Tuesdays as extra security. Chauvin worked as an off-duty police officer for the club for nearly 17 years, Santamaria said.
“I wouldn’t characterize them as knowing each other,” she told CNN’s Josh Campbell in an interview.
But, she added, “We all worked together certain nights and they would have crossed paths.”
Santamaria said she couldn’t believe what she was seeing when she watched footage of the two employees, one under arrest and one face down on the pavement.
“I kept yelling at my phone, telling Chauvin to get off of him. It’s horrible. It’s absolutely beyond words,” she said. “And having known Chauvin, I can’t believe he didn’t have the humanity to listen to this poor man begging for his air and his life.”
His wife had filed to dissolve their marriage
The day after Chauvin’s arrest, an attorney for his wife Kellie filed for a dissolution of marriage.
“This evening, I spoke with Kellie Chauvin and her family. She is devastated by Mr. Floyd’s death and her utmost sympathy lies with his family, with his loved ones and with everyone who is grieving this tragedy. She has filed for dissolution of her marriage to Derek Chauvin,” a statement from Sekula Family Law office read.
“While Ms. Chauvin has no children from her current marriage, she respectfully requests that her children, her elder parents, and her extended family be given safety and privacy during this difficult time.”
The pair owns a townhouse in Windmere, Florida, Orange County property records show. Peaceful protests were held there before Chauvin’s arrest when it was rumored Chauvin had left Minnesota to hole up in Florida. The Orange County Sheriff’s Office said he wasn’t in the home and had no plans to be, and shortly thereafter, he was arrested in Minnesota.
