Police arrested the estranged brother-in-law of Jennifer Hudson on Monday in the deaths of the entertainer's mother, brother and young nephew, taking him from a prison where he had been held on a suspected parole violation.
William Balfour was arrested at Stateville Correctional Center and released to detectives in the shooting deaths of the singer and Oscar-winning actress' relatives, said Chicago police spokeswoman Monique Bond.
Until Monday, police had identified Balfour, 27, only as a "person of interest" in the investigation. He had not been charged by Monday evening, said Andy Conklin, a spokesman for the Cook County state's attorney's office.
The bodies of Jennifer Hudson's mother, Darnell Hudson Donerson, and brother, Jason Hudson, were discovered Oct. 24 at the family's home on the South Side of Chicago. The body of 7-year-old Julian King was found three days later in a sport utility vehicle on the West Side. All three had been shot.
Police took Balfour into custody the same day the bodies of Donerson and Hudson were discovered. After 48 hours — the longest Chicago police can hold a person without charges — Balfour was taken by the Illinois Department of Corrections on the suspected parole violation.
Balfour — Julian's stepfather and the estranged husband of Jennifer Hudson's older sister, Julia Hudson — served seven years for a 1999 attempted murder and vehicular hijacking conviction.
His mother, Michelle Davis-Balfour of Chicago, told reporters outside a police station Monday night that authorities don't have a case against her son.
"If they found gun powder on his hands, you got a case; if they found a gun on him, he had a case; if they found a fingerprint on the truck that he did this, you got a case; but they don't have nothing," Davis-Balfour said.
Balfour had refused to take a lie-detector test and stopped cooperating with detectives, according to a police official who was not authorized to discuss the case publicly and spoke on condition of anonymity.
Police have confirmed they found the gun used in the killings. The .45-caliber gun was discovered Oct. 29 in a vacant lot in the West Side neighborhood where the King's body was found a few days earlier.
Bond declined to discuss any evidence Monday. But after a hearing at the prison, the chairman of the Illinois Prisoner Review Board said a woman had told authorities that a gun used in the slayings was "identical" to the gun that was recovered.
At the time, board Chairman Jorge Montes said the evidence was key to a decision finding probable cause that Balfour violated his parole and should remain locked up pending a Dec. 3 hearing before a review board panel.
