Several hundred people, led by clergy members, marched from a Ferguson church to the city's police headquarters on Monday, part of a four-day weekend of rallies and marches.
The rally included a listing of names of people killed across the country by police officers. It was among many events since Friday.
Protests have been common in Ferguson since Michael Brown, an unarmed, black 18-year-old, was killed by a white Ferguson officer on Aug. 9. Tensions escalated last week when a white police officer in St. Louis shot and killed 18-year-old Vonderrit Myers Jr. Police say Myers, who also was black, shot at the officer first.
Earlier Monday, hundreds of people marched to St. Louis University.
Organizers promised civil disobedience on Monday, but by midday, no arrests had been made.
