William Balfour, the estranged brother-in-law of Jennifer Hudson, has been arrested in the murders of the actress/singer’s mother, brother and nephew. Hudson’s mother, Darnell Donerson, and brother, Jason Hudson, were found shot to death in their South Side Chicago home Oct. 24. Hudson’s 7-year-old nephew, Julian King, was found dead from gunshot wounds in an abandoned SUV Oct. 27. Balfour has been jailed for violating parole for an attempted murder in 2006. Family members say he and wife Julia Hudson had a rocky relationship, and that he had been kicked out of the family’s home. Given her behavior early on in the ordeal, something tells me Julia isn’t too broken up about this.
