8A grand jury has reached a decision on whether to indict Darren Wilson, the white Ferguson, Mo. police officer whose fatal shooting of an unarmed black teenager sparked days of turbulent protests, sources close to the process said. Sources said that press conferences are being prepared by the county prosecutors’ office and the Missouri governor. Those press conferences will likely come later today.
