(CBS/AP) CHICAGO - There appears to be no "smoking gun" when it comes to DNA in the case of the man accused of killing actress Jennifer Hudson's mother, brother and nephew.

A forensic scientist testified on Wednesday that the DNA of William Balfour, the man on trial for allegedly killing Hudson's family members, was not on the murder weapon.

Illinois State Police analyst Pauline Gordon said Wednesday she tested the .45-caliber pistol and found a limited amount of DNA belonging to a male but it excluded Balfour.

Gordon also explained DNA would not be present if the killer was wearing gloves or wiped the weapon clean.

Balfour is accused of gunning down 29-year-old Jason Hudson, 57-year-old Darnell Donerson and 7-year-old Julian King on Oct. 24, 2008.

Earlier, Illinois State Police forensic analyst Robert Berk testified he found gunshot residue on the ceiling above the rear seat of the Jason Hudson's SUV and on a steering wheel cover in Balfour's automobile.
