In an unexpected turn of events, Hakim Muhammad, accused in the November 2009 murder of his wife Sheila Muhammad, took the stand on his own behalf during his trial Thursday, insisting he did not kill his wife. Chief Public Defender Steven Purvis told Rockdale Superior Court Judge Sidney Nation that he had advised his client not to testify, and the proceedings were delayed for several minutes while Purvis and Muhammad moved to another part of the courtroom to confer. Muhammad did not change his mind.
