The events remained peaceful but boisterous gatherings lasted into the night. Vietnam-era peace activists, New York City seminarians and hundreds of fast-food workers bused in from Chicago, Nashville and other cities marched alongside local residents, spurred by a national campaign dubbed Ferguson October.

Outside Busch Stadium in downtown St. Louis, where the Cardinals hosted the San Francisco Giants in the first game of the National League Championship Series, several dozen protesters stood on the sidewalk, chanting and holding signs.

Four days of planned events began Friday afternoon with a march outside the St. Louis County prosecutor's office. Protesters renewed calls for prosecutor Bob McCulloch to charge Darren Wilson, a white Ferguson officer, in the Aug. 9 death of Brown, a black, unarmed 18-year-old. A grand jury is reviewing the case and the Justice Department has opened a civil rights investigation.

On Saturday night, a smaller group of demonstrators joined Brown's mother at a prayer vigil and protest outside the Ferguson apartment complex where her son was shot and killed two months ago. The group then marched to the Ferguson police department.

Organizers said beforehand that they expected as many as 6,000 to 10,000 participants for the weekend's events. Police were not able to provide a crowd estimate Saturday, but organizers and participants suggested the march's size may have approached 3,000.

Since Brown's death, three other fatal police shootings of black males have occurred in the St. Louis area. The most recent involved an off-duty St. Louis officer who was working for a private neighborhood security patrol when he shot and killed 18-year-old Vonderrit D. Myers on Wednesday night.

The white officer, whose name hasn't been released, fired 17 rounds after police say Myers opened fire. Myers' parents say he was unarmed, and many speakers at a Saturday rally echoed those doubts.
