The two-year anniversary of Michael Brown's fatal shooting by an officer will be marked with a memorial service and a moment of silence on the Ferguson street where he died.

The events are planned late Tuesday morning on Canfield Drive.

The black, unarmed 18-year-old was shot by Ferguson officer Darren Wilson on Aug. 9, 2014. A St. Louis County grand jury and the U.S. Justice Department determined that no charges should be filed against Wilson, who resigned that November.

The shooting was a catalyst in the national Black Lives Matter movement and led to months of protests in Ferguson.

It also led to a Justice Department investigation that found troubling practices in Ferguson's criminal justice system, resulting in an agreement this year between the federal agency and the city calling for sweeping changes.
