William Balfour, the estranged husband of Oscar-winning actress and singer Jennifer Hudson’s sister, pleaded not guilty on Tuesday to charges of first-degree murder and home invasion, according to the Associated Press. Balfour is accused of killing Hudson’s mother, brother, and nephew in Chicago last October. He is currently being held without bail in Illinois, and is due to appear in court next on Jan. 27.

Hudson has kept a low profile since her family tragedy, but she is due to sing the national anthem at the Super Bowl on Feb. 1.
