Tuesday, the Chicago police revealed that they had charged Jennifer Hudson’s brother-in-law William Balfour with the murders of the actress-singer’s mother, brother and nephew, adding the evidence was enough for a conviction to follow.

Authorities informed that the murder weapon, physical evidence they had, along with a testimony were sufficient for a jury to decide to convict 27-year-old Balfour in the case.

Moreover, they stated that the man, who is the estranged husband of Jennifer Hudson's elder sister, Julia, had committed the murders on October 24 (victims being Hudson’s mother and brother) after he had had a domestic fight with his wife.

At that time, the Oscar-winning actress’ mother Darnell Donerson, 57, and brother, Jason Hudson, 29, were both found dead at the former’s home on the South Side of Chicago.

Four days later, Julian King’s body, Hudson’s nephew and Julia’s son, aged 7, was found in the West Side neighbourhood inside an SUV, while nearby, the murder weapon was discovered by the police.

William Balfour was charged with the three murders and is also facing a home invasion charge. His mother Michele Balfour has told reporters that Balfour was innocent claiming that the police had relied on one of his girlfriends’ testimony, who was facing a drug charge.

Furthermore, she added that her son loved Darnell Donerson even more than he did her.

Chicago Police Superintendent Jody Weis revealed that the girlfriend’s testimony had not been obtained in exchange for a deal concerning her own drug charges.
