*A St. Louis County grand jury has completed deliberations and reached a decision in the case of Ferguson Police Officer Darren Wilson, reports USA Today.

CNN and The Washington Post reported that prosecutor Robert McCulloch will announce later today whether Wilson, 28, will face charges in the death of Michael Brown, 18, on a Ferguson street Aug. 9. The sources did not know what decision will be announced.

The city has been on edge in anticipation of a decision. Some businesses have been boarded up, and activists are prepared to protest.

For the grand jury, the key question is whether white police officer Darren Wilson will face charges in the August 9 shooting death of Brown, 18, who was African American.

The 12-member grand jury is deciding whether Wilson should be charged with any of several possible crimes, including: first-degree murder, second-degree murder, voluntary manslaughter or involuntary manslaughter, said Ed Magee, a spokesman for the Prosecuting Attorney’s Office.

The grand jury can issue an indictment on any of those four charges. It also can add a charge of armed criminal action, authorities said.

But the grand jury, which received the Missouri statutes for self-defense and the police use of deadly force, may also choose not to indict Wilson.
