Authorities have released evidence presented to the grand jury that decided not to indict Darren Wilson, but some facts won't be made public—including who was on the jury. St. Louis County Prosecuting Attorney Robert McCulloch says the 12 grand jurors were "working, not retired, working professional, blue collar," the Washington Post reports. It takes nine votes to indict in Missouri, and the vote count will not be made public. It is a "very secret process," McCulloch says. "We aren't allowed to ask or to discuss the vote or deliberations." According to the AP, the grand jury was composed of six white men, three white women, two black women, and one black man.
