Hundreds of mourners wearing COVID-19 masks packed into Shiloh Temple International Ministries to remember Wright, a 20-year-old father of one who was shot by a police officer on April 11 in the small city of Brooklyn Center.

The Reverend Al Sharpton was to deliver the eulogy and told the Associated Press that he would first pay tribute to Wright, "a young man just at the beginning of life, full of life".

He said he would also use his remarks to remind those in attendance or watching from afar that the fight for justice didn't end when white former Minneapolis police officer Derek Chauvin was found guilty of murder and manslaughter for holding a knee to Floyd's neck, choking off his breathing until he went limp last May.

"We should not think that, because we won one battle with Chauvin, the war is over, or that if we do not get justice for this case, that we will undo what we were able to do with George Floyd," Sharpton said.

"This is round two, and we must win this round."

At Floyd's Minneapolis funeral last year, Sharpton put Floyd's death in the context of brutality long felt by blacks in the US, saying: "The reason we could never be who we wanted and dreamed to be is you kept your knee on our neck."

"What happened to Floyd happens every day in this country," Sharpton said at the time.

"It's time for us to stand up in George's name and say, 'Get your knee off our neck!"'

Among those attending Wright's funeral were Valerie Castile, whose son Philando Castile died after being shot by a police officer during a traffic stop in a Minneapolis suburb in 2016, and Gwen Carr, the mother of Eric Garner, who was filmed saying "I can't breathe" in a fatal 2014 encounter with New York City police.

US Senator Amy Klobuchar, Governor Tim Walz and Minneapolis Mayor Jacob Frey also attended.

More than a dozen members from a local militia, the Minnesota Freedom Fighters, provided security.
