The body of a boy believed to be the missing nephew of singer/actress Jennifer Hudson was discovered Monday three days after Hudson's mother and brother were found shot to death in their Chicago home, dpa reported.
The boy had not been seen since the discovery of Darnell Hudson Donerson, 57, and Jason Hudson, 29, by a family member Friday.
The body was found in the rear seat of white sports utility vehicle registered to Hudson's deceased brother Jason, Chicago police said.
Police have taken into custody William Balfour, the estranged husband of Hudson's sister Julia, but have so far not named his as a suspect in the crime.
Hudson offered a 100,000-dollar reward over the weekend for information leading to the missing 7-year-old boy Julian King.
Police believe the two were murdered in a family argument. Hudson had to identify the dead bodies, E!News reported.
Hudson sang the American national anthem at the Democratic presidential nominating convention in Denver, Colorado, in August. Democratic nominee Barack Obama and wife Michelle have sent her condolences.
Just weeks ago the singer, who broke onto the scene in the talent programme American Idol, released her debut album, Jennifer Hudson. She won an Academy Award for her role in Dreamgirls.
