One year after the shooting that cast greater scrutiny on how police interact with black communities, the death of 18-year-old Michael Brown in Ferguson, Missouri, will be marked with a somber march and a moment of silence.

The march late Sunday morning begins at the site where Brown, who was black and unarmed, was fatally shot by Ferguson officer Darren Wilson on Aug. 9, 2014. A grand jury and the U.S. Department of Justice declined to prosecute Wilson, who resigned in November, but the shooting touched off a national "Black Lives Matter" movement.

After the moment of silence, a service commemorating the anniversary is planned at a Ferguson church. The events are among several this weekend in Ferguson and nearby St. Louis.
