Ferguson, Missouri (CNN) -- Two months. It looks like it might be that long before a local grand jury decides whether to bring charges in the death of Michael Brown -- the loud, passionate calls for swift justice notwithstanding. The shooting of the African-American teenager by a white Ferguson, Missouri, police officer has sparked days of demonstrations and nights of often violence protests in the St. Louis suburb. St. Louis County Prosecuting Attorney Robert McCulloch told CNN affiliate KMOV that his office planned to begin presenting the case to a grand jury Wednesday. The grand jury could levy significant charges against Darren Wilson, the police officer who shot and killed the 18-year-old Brown.
