Prosecutors going into a third day of evidence at the trial of the man who allegedly murdered Jennifer Hudson's family are expected to focus on the youngest victim, the actress and singer's 7-year-old nephew.

They're likely to pick up Wednesday where they left off with testimony about Julian King's abduction and slaying.

A police officer Tuesday described how he initiated a city-wide search for the boy, nicknamed Juice Box.

Hudson's former brother-in-law, William Balfour, allegedly killed her mother and brother at their Chicago home, then drove off with Julian in an SUV. He allegedly shot him in the head behind a front seat.

Prosecutors Tuesday showed jurors photographs of the bloodied bodies of Hudson's mother and brother. Hudson left the courtroom before the grisly pictures were projected onto a screen.
