Chicago Tribune reported that the chrome-and-black .45-caliber pistol found by the Chicago police a block from where 7-year-old Julian King's body was discovered, was indeed the weapon used for the slaying. Furthermore, the publication noted that the police are investigating whether it is the gun once belonged to Jason since Jennifer's slain brother allegedly has an identical gun which he said to be stolen months prior to the murder. So far, authorities haven't put charges on anyone for the killings. However, Jennifer's brother-in-law and Julia's estranged husband, 27-year-old William Balfour, has been called a "person of interest" on the case. He is being held in custody on a parole violation.Jennifer Hudson’s brother might have once possessed the stolen handgun that cops suspect was used to kill him and two other members of the actress’ family, the Chicago Tribune reported yesterday. The brother, Jason Hudson, 27, told neighbors his weapon was swiped months ago, the Tribune said. Jason was found shot dead along with his mother on Oct. 24. Hudson’s nephew, Julian King, 7, was abducted and found shot to death with a .45-caliber Sig Sauer pistol three days later in an SUV. William “Flex” Balfour, the estranged husband of Jennifer Hudson’s sister, is under arrest.
