Chicago cops have confirmed -- the gun found last Wednesday is the same one used to murder three members of Jenifer Hudson's family.
Police found a .45 caliber Sig-Sauer semiautomatic pistol a block from where a vehicle was part containing the body of Jenifer's 7-year-old nephew Julian King. Cops knew almost immediately the gun was a match because of unfired bullets synced up with the casings found at the murder scene.
Police also are investigating whether the weapon may have once belonged to Jason Hudson.
The U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives determined the weapon was originally owned by someone in Michigan who had reported it stolen. Investigators now need to follow the path of the gun that takes them to Chicago.
