Jennifer Hudson's estranged brother-in-law was arrested Monday in the shooting deaths of the Academy Award-winner's mother, brother and young nephew. According to Chicago officials, William Balfour was arrested at Stateville Correctional Center, where he was being held on a suspected parole violation, and is being accused of murdering the singer/actresses family.

Balfour was originally listed as a "person of interest" in the investigation. Balfour had not been formally charged as of Monday night and proclaims is innocence. "He vehemently denies that he is guilty in this case," Balfour's attorney Joshua Kutnick told reporters yesterday. "Any evidence pointing to Mr. Balfour is not even thin. It is very, very weak," Kutnick said.

The bodies of Hudson's mother Darnell Hudson Donerson, and brother, Jason Hudson, were discovered on Oct. 24 at the family's Chicago residence. The body of the star's 7-year-old nephew, Julian King, was found three days later in a vehicle on the West Side of Chicago. Police found the .45-caliber gun used in the killings a few days after discovering King's body.
