BEIJING, Oct. 30 (Xinhuanet) -- Chicago police on Wednesday found a handgun just a block from the spot where Oscar-winning actress Jennifer Hudson's 7-year-old nephew Julian King was shot to death, media reports said.

    The gun matches the caliber of the weapon used in the murders of Hudson's three family members, who also include Darnell Donerson, 57 and Jason Hudson, 29.

    The weapon was being tested to compare with ballistics taken from where Hudson's family members were slain, police said.

    According to the Chicago Sun-Times, the gun and other as-yet-undisclosed evidence was discovered by a police recruit, who was conducting a routine search in connection with the investigation, at 1:30 p.m. in an empty trash-strewn lot on 14th Street between Kildare and Kolin Avenues on the city's West Side.

    Also, at least one witness claims to have seen someone driving a vehicle matching the white Suburban through the alley toss something from the window, a source said.

    Julian King's body was discovered Monday morning, slumped in the back seat of a Chevy Suburban.

    Julian, who had been shot twice in the head, had been missing since Friday, when Jason Hudson and Donerson were found shot to death in the family's home.
