Balfour is the estranged husband of Jennifer Hudson's sister, Julia Hudson. He's charged in the October deaths of the Hudson sisters' mother, Darnell Donerson, their brother, Jason Hudson, and Julia Hudson's 7-year-old son, Julian King.
Balfour has pleaded not guilty. He's been held in a state prison in Joliet on a parole violation.
Prosecutors allege Balfour shot the three in a jealous rage.
The judge set Feb. 23 as the next hearing in the case.
