Darren Wilson spent nearly four hours in front of a St. Louis County grand jury on Tuesday, the Post-Dispatch reports, despite not being required to testify. An anonymous source called Wilson “cooperative,” and said he has also given his side of the story twice to local investigators and once to federal investigators. The grand jury has until January 7, 2015 to bring criminal charges against the officer after a judge extended the 12-member session for as long as allowed by law.
