Thousands are set to gather in Houston, Texas, to remember George Floyd, an unarmed black man whose death in police custody sparked global protests.
Mr Floyd lived in the city before moving to Minneapolis, Minnesota, where he died on 25 May.
A six-hour public viewing of his body will be held at The Fountain of Praise church in Houston.
In Minnesota, a white police officer accused of killing Mr Floyd will appear before a judge for the first time.
Derek Chauvin, who knelt on Mr Floyd’s neck for almost nine minutes, has been dismissed and charged with second-degree murder. Three other officers who were at the scene have been sacked and charged with aiding and abetting.
On Tuesday, a private funeral service will be held for Mr Floyd in Houston.
Memorial services have already been held in Minneapolis and North Carolina, where Mr Floyd was born.
It is believed a family member escorted Mr Floyd’s body on a flight to Texas late on Saturday.
Democratic US presidential candidate Joe Biden is expected to visit Mr Floyd’s relatives in Houston to offer his sympathies. Aides to the former vice-president said he would also record a video message for Tuesday’s service.
The public farewell will follow social distancing requirements, with only 15 guests allowed in the church at a time, local media report.
Those in attendance will be required to wear gloves and masks before entering.
Anti-racism protests started by Mr Floyd’s death are now entering their third week in the US. Huge rallies have been held in several cities, including Washington DC, New York, Chicago, Los Angeles and San Francisco.
With the rallying cries “Black Lives matter” and “No Justice, No Peace”, the demonstrations are among the largest US protests against racism since the 1960s. Saturday’s gatherings included a protest in the Texas town of Vidor, once infamous as a stronghold of the Ku Klux Klan white supremacist group.
Episodes of looting and violence have, however, been reported among the peaceful rallies, and President Donald Trump threatened to call up troops to quash the protests.
Security measures were lifted across the US on Sunday as unrest started to ease. New York ended its nearly week-long curfew, and Mr Trump said he was ordering the National Guard to start withdrawing from Washington DC.
On Sunday, nine of 13 Minneapolis City Council members pledged in front of hundreds of protesters to dismantle the local police department and instead create “a new model of public safety that actually keeps our community safe”.
It is not yet clear what form the changes will take, or how soon they can happen.
Democrats in Congress are expected to present sweeping legislation on police reform on Monday.
