Multiple sources tell CBS News that the announcement of a grand jury decision in the Michael Brown shooting case is not expected before Monday.
A 12-member jury is weighing whether to indict Ferguson police officer Darren Wilson, who is white, with fatally shooting Brown, a black teenager who was unarmed, on Aug. 9.
The case triggered months of protests on the streets of Ferguson, some of which turned violent.Some activists are calling for widespread changes in the way police officers interact with the community, race relations and socioeconomic factors that led to the unrest.
To that end, Missouri Gov. Jay Nixon appointed 16 people to the Ferguson Commission, which will study the issues and recommend action steps in a Sept. 2015 report.
The community is bracing for the grand jury's report, with Brown's family joining President Obama and Attorney General Eric Holder urging people to remain peaceful.
Federal, state and local law enforcement agencies have deployed additional officers to the area in advance of any demonstrations, including about 100 FBI agents. Nixon has also activated the National Guard, and schools in Ferguson and nearby communities have canceled classes.
