OAKLAND (CBS / AP) ― The admitted killer of an Oakland journalist on Tuesday insisted under cross-examination that the leader of a once-influential community group ordered him to commit several murders.

For a second straight day, defense attorneys attacked Devaughndre Broussard’s credibility. During one heated exchange, defense attorney Gene Peretti asked Broussard if former Your Black Muslim Bakery leader Yusuf Bey IV ordered him to kill Oakland Post newspaper editor Chauncey Bailey.

“He did,” Broussard said.

“Are you sure about that?” Peretti asked.

“I’m sure,” Broussard said.

“You’re telling the truth now?” Peretti countered. “This is not one of the times you’re lying?”

“No!” Broussard said.

Broussard has admitted to fatally shooting Bailey and another man in 2007. Under a plea deal, Broussard has been testifying against Bey and bakery associate Antoine Mackey.

Bey is accused of ordering the killing of Bailey to stop an investigative piece about the bakery’s financial troubles from being published. He’s also accused of ordering the deaths of Odell Roberson, Jr., and Michael Wills. Mackey is accused of killing Wills and with helping Broussard in the murders of Bailey and Roberson.

In one chilling moment on Tuesday, Peretti asked Broussard if he was getting back at Bey, who told an Oakland police detective that Broussard killed Bailey.

Broussard, a 23-year-old former handyman, looked directly at Bey and said, “Yeah!”

Peretti, trying to make the point that Broussard killed Roberson independently, also asked if Bey specifically used the word “kill” when ordering Roberson’s death.

Broussard said he and Bey were alone when the former bakery leader told him to “get on” Roberson. Broussard said it meant that Bey wanted Roberson killed.

Outside the courtroom, Peretti maintained that Broussard is lying.

“He’s certainly telling the truth about the fact that he’s a murderer — he’s killed two people in cold blood, and that’s true and he sticks to that, and that’s something he knows,” Peretti said. “But when he starts describing other people’s involvement and the details of it, it all of a sudden gets very inconsistent and very hazy.”
