William Balfour, the convicted felon being held in the killings of Jennifer Hudson’s mother, brother, and nephew, will remain in prison after authorities say his girlfriend reported seeing him with a gun that matched the murder weapon.

The Illinois Prisoner Review Board decided there was reason to believe that the 27-year-old had violated his parole and will hold him until a December 3rd hearing.

Balfour is the estranged husband of Hudson’s sister, Julia.
