The convicted felon suspected in the killings of the mother, brother and nephew of singer Jennifer Hudson has a parole hearing Monday and could be released if an administrative officer finds no reason to hold him.

No one has been charged in the shootings, but authorities have called 27-year-old William Balfour a "person of interest."

Balfour is in custody on a parole violation. He is the estranged husband of Julia Hudson, sister of the singer and actress.

The chairman of the Illinois Prisoner Review Board, Jorge Montes (HOR'-hay MON'-tehs), says that if an administrative officer finds cause to continue holding Balfour, the case then would go to a review board for a hearing.

However, Montes says "conceivably" Balfour could be released.
