Social media reports about damage to the memorial started early Friday. Supporters were out before dawn rebuilding the memorial, which sits in the middle of Canfield Drive in Ferguson.

It is not known who struck the memorial, which went up Aug. 9, soon after the black 18-year-old was shot and killed by a white police officer. The shooting spurred massive protests. A grand jury decided last month not to file charges against the officer, Darren Wilson. Wilson later resigned from the police department.

A second memorial to Brown, nearby but off the street, caught fire in September, angering supporters. The cause of the blaze was not determined.
