A Black man who died three days after being beaten in a traffic stop. Video footage of Nichols’ arrest was released Friday evening.

Here is what we know so far about the police encounter, his death and the aftermath.

Four of the five former Memphis Police officers indicted for their role in the death of Tyre Nichols were suspended or received a written reprimand during their tenure with the department, with only one charged officer avoiding internal disciplined during his tenure.

In personnel files obtained through a public records request by The Commercial Appeal, four officers were either reprimanded or suspended for their failure to report when they used physicality, failing to report alleged domestic violence, or for damages sustained to their squad cruisers.

The four former officers indicted who had either a reprimand or a suspension were Demetrius Haley, Desmond Mills, Jr., Justin Smith, and Emmitt Martin III. Tadarrius Bean, who was also fired and indicted, did not have any reprimands or suspensions in the records viewed by The Commercial Appeal.

Who was Tyre Nichols, and what do we know about his arrest?

Nichols, a 29-year-old who worked at FedEx, was the father of a 4-year-old boy. The youngest of four siblings, he was especially close with his mother. He has been described by friends and family as joyful and spiritual, and he was an avid skateboarder and photographer.

“This man walked into a room, and everyone loved him,” said Angelina Paxton, a friend who attended his memorial service.

Nichols grew up in Sacramento before moving to Memphis, where he lived with his mother and stepfather. Friends from his teenage years in California spoke to CBS Sacramentoabout how much joy he brought to those around him.

“I know Tyre. I know how great he was,” said Jerome Neal, who had just visited Nichols in Memphis in November. “I see him interacting with like almost everybody at the skate park when I’m with him. He was just well-loved.”

“He just touches anybody who gets around him,” another friend, Austin Robert, told the station. “He’s a fantastic person and that’s how I really want everybody to remember him.”

Rev. Al Sharpton singled out the five Black Memphis police officers indicted for their roles in Nichols’s death.

Noting that the alleged crimes took place not far from the Lorraine Motel, where Martin Luther King Jr. was murdered on April 4, 1968, while waging a protest campaign to try to ensure the safety of Black workers in the city, Sharpton drew a line connecting the legacy of the slain civil rights hero to the killing of Nichols.

“The reason why, Mr. and Mrs. Wells [Nichols’s stepfather and mother], what happened to Tyre is so personal to me is that five Black men that wouldn’t have had a job in the police department, would not ever be thought of to be in an elite squad in the city that Dr. King lost his life, not far away from that balcony, you beat a brother to death,” Sharpton said in his address.

“There’s nothing more insulting and offensive to those of us that fight to open doors that you walk through those doors and act like the folks we had to fight for to get you through them doors,” Sharpton added. “You didn’t get on the police department by yourself. The police chief didn’t get there by herself. People had to march and go to jail, and some lost their lives to open the doors for you, and how dare you act like that sacrifice was for nothing!”
