Fiancee of ex-NFL star testifies in his double-murder trial (The Associated Press)

Former NFL star Aaron Hernandez’s fiancee testified in his double-murder trial Thursday that she learned to keep her mouth shut and ”not to ask any questions” in certain situations. Shayanna Jenkins-Hernandez testified against Hernandez under a grant of immunity from prosecutors. Hernandez, a former tight end for the New England Patriots, is accused of fatally shooting two men in Boston in July 2012 after an encounter at a Boston nightclub.
