St. Louis County Circuit Court administrator Paul Fox said there are three African-Americans -- one male, two females -- and nine whites -- six males, three females -- on the 12-member panel. There are a total of seven men and five women.
No information was given about the ages or occupations of any on the grand jury.
This information on the jury's makeup comes as a key complaint among Brown family supporters continues: that the man whose office is tasked with making the case to the grand jury -- St. Louis County Prosecuting Attorney Bob McCulloch -- is too cozy with law enforcement, does not have a good relationship with the African-American community and thus should be replaced.
For his part, McCulloch has indicated he won't recuse himself, saying he's simply doing the job he was elected to do.
The county grand jury was randomly selected from an approved pool and has been seated since May according Paul Fox, the director of judicial administration for the St. Louis County Circuit Court.
In many locales, grand juries hear numerous cases during their terms, which cover a specified period of time instead of the duration of a specific case.
Unlike a jury in a criminal case, which convicts someone if jurors are convinced of guilt "beyond a reasonable doubt," a grand jury decides if there is "probable cause" -- based on testimony and evidence presented, in the absence of a judge -- to charge someone with a crime. In Missouri, they don't have to be unanimous to press such an indictment, as long as nine of the 12 agree on a charge.
