Federal trial set to begin for ex-officers charged in Tyre Nichols' death

• The Memphis Police Department (MPD) later publicly released graphic footage of the encounter, which drew horrified reactions from the public and spurred protests.
• The police force fired the officers following Nichols' death.

What they're saying: "We've been able to grieve a little and heal a little — however, now that this trial is coming up, we're going to have to relive all of that again," said RowVaughn Wells, Nichols's mother, told the New York Times.

Catch up quick: Five former Memphis police officers — Tadarrius Bean, Demetrius Haley, Emmitt Martin III, Desmond Mills Jr. and Justin Smith — were indicted in state and federal cases last year in connection with the incident.

• Mills pleaded guilty to federal charges last November as part of a plea agreement. A second, Martin, did the same last month.
• Their trials on state charges, including second-degree murder, are pending until federal proceedings are complete.

Driving the news: The federal trial beginning Monday will focus on Bean, Haley and Smith, who have all pleaded not guilty.

• The trial is expected to last three or four weeks and could see both Mills and Martin testify, per AP.
• The officers face the possibility of life in prison if found guilty on all of the federal charges.
