Oscar winner Jennifer Hudson's 7-year-old nephew was found dead in the back of an SUV on Monday, ending a frantic search that began after the shooting deaths of Hudson's mother and brother three days earlier.
The singer and actor was among seven family members and close friends who cried and held hands as they identified Julian King's body from a wall-mounted video screen that showed his face.
The boy, like his grandmother and uncle, had been shot, said Chicago police spokeswoman Monique Bond. The medical examiner's office planned an autopsy today.
A motive remained unclear Monday, but Chicago police Superintendent Jody Weis said, "It wasn't a case of a stranger-type homicide."
Police have characterized the slayings as "domestic related" and authorities have been questioning Julian's stepfather, who has been estranged from the boy's mother and is being held on a parole violation. No one has been charged in the slayings.
Julian's body was found in the rear seat of the SUV, which matched the one mentioned in an Amber Alert for the boy. It was parked on the street in a neighborhood of brownstone homes and apartment buildings.
The vehicle was about 10 miles from the house where the other victims were found, which was where Julian lived and where Hudson grew up.
Hudson had offered $100,000 Sunday for information leading to the safe return of her nephew, the son of her sister, Julia Hudson.
The Amber Alert had listed William Balfour, the estranged husband of Julia Hudson, as a suspect in a "double homicide investigation." He is not the boy's father and has not been charged in the slayings.
Weis said Monday that Balfour "remains a person of interest."
Records show Balfour, who was taken Sunday to the Illinois Department of Corrections on a parole violation, spent nearly seven years in prison for attempted murder, vehicular hijacking and possessing a stolen vehicle.
Hudson, 27, who won an Academy Award for best supporting actress in 2007 for her role in Dreamgirls, returned to Chicago to be with her family during the weekend. She also identified the bodies of her mother and brother.
