From the St. Louis Post-Dispatch:
Ferguson police Officer Darren Wilson testified for almost four hours Tuesday in front of a St. Louis County grand jury investigating the Aug. 9 shooting of Michael Brown, a source with knowledge of the investigation said Wednesday.
Wilson was not obligated to testify, and has also spoken with St. Louis County investigators twice and federal investigators once, the source said. The source said that Wilson had been “cooperative.”
The grand jury term was set to expire last week, but was extended until January 7, 2015.
