During cross examination Tuesday, the attorney for Yusuf Bey IV questioned Devaughndre Broussard about the killing of Odell Roberson, Jr., in July 2007.
Broussard testified that he couldn't say if Bey actually used the word "kill."
Broussard has admitted to fatally shooting Roberson as well as Oakland Post Editor Chauncey Bailey in August 2007.
Broussard says Bey ordered both killings while leading Your Black Muslim Bakery and that co-defendant Antoine Mackey also participated in the murders.
Bey and Mackey have pleaded not guilty.
Attorneys for Bey and Mackey began their cross-examination Monday by attacking Broussard's credibility.
