Officials with St. Louis County announced Monday evening that Ferguson Police Officer Darren Wilson will not face criminal charges after fatally shooting unarmed civilian Michael Brown in August.

A 12-person grand jury comprised of three black and nine white members reached their decision Monday afternoon, but county officials waited until evening to make the announcement. The grand jury was considering charges of first-degree murder, second-degree murder, voluntary manslaughter and involuntary manslaughter, with the possible addition of a charge of armed criminal action.

While the grand jury’s decision means Wilson will not be charged with a crime, he and the Ferguson Police Department may still face civil lawsuits from Brown’s family. Two federal civil rights investigations in connection to the case are also underway, and both the FBI and the Justice Department are investigating Ferguson PD’s past treatment of minorities.

Brown’s family, President Obama and Missouri Governor Jay Nixon have been urging peaceful protest. Last week, Nixon declared a state of emergency and requested a National Guard presence on the streets of Ferguson, a decision of which many have been highly critical.

The evidence considered by the grand jury has not yet been disclosed, though St. Louis County Prosecutor Robert McCulloch has said he will seek to have it made public.
