Jennifer Hudson's brother-in-law, suspected of killing three family members, appears before an Illinois parole board Monday to seek his freedom, officials say.

William Balfour, 27, the estranged husband of Hudson's sister, Julia, will appear before the Illinois Prisoner Review Board while the police investigation into the triple homicide in Chicago continues, the Chicago Tribune reported Sunday.

Hudson's 57-year-old mother, Darnell Donerson, was shot and killed in Chicago Oct. 24 along with the "Dreamgirls" star's 29-year-old brother, Jason.

The body of Hudson's 7-year-old nephew, Julian King, was found days later in a vehicle elsewhere in the city.

Balfour has been questioned in the three deaths but has not been charged. He was arrested Oct. 26 for allegedly violating his parole from a 1999 attempted murder conviction and has been held at the Stateville Correctional Center, the Tribune noted.
