Julian King had been missing since Hudson's mother and brother were found shot to death in the home they shared on Friday. Police spokeswoman Monique Bond says the boy also had been shot.
Julian had been the subject of a frantic search since the killings, which police have characterized as "domestic related."
Police say Hudson was among seven family members and close friends who identified the body from a video image at the Cook County Medical Examiner's office Monday.
No one has been charged in the slayings. Authorities have been questioning the estranged husband of Hudson's sister.
