Chicago Police have arrested William Balfour,  the estranged brother-in-law of R&B Singer and actress Jennifer Hudson.  He will be charged with three counts for the October slayings of Hudson’s mother, brother and young nephew, authorities said today. “He was released to Chicago detectives,” Chicago Police Department spokeswoman Monique Bond said. Balfour, 27, who was married to Hudson’s sister Julia, was a person of interest after the slayings and was detained and questioned by police but not charged. Balfour, who was also imprisoned for violating his parole on a previous attempted murder conviction, was scheduled to have a hearing on Wednesday. Police did not reveal the evidence that led to Balfour’s arrest but he now faces charges for the slaying that tore the Oscar winner’s family apart and grabbed the attention of the nation in late October. Balfour will be charged for the shooting deaths of Hudson’s mother, Darnell Donerson, 57, brother, Jason Hudson, 29, and 7-year-old nephew, Julian King. Donerson and Jason Hudson were found shot to death on October 24 in Donerson’s home on the South Side of Chicago. Four days later, Hudson’s young nephew’s body was found in a stolen sport utility vehicle parked and abandoned on the West Side of the Windy City. A gun reportedly used in the slayings was found close to the SUV.
