UPDATE: Jennifer Hudson's Brother, Mother Found Brutally Murdered On Friday; Police Confirm Death Of Hudson's 7-Year-Old Nephew

After positively IDing the bodies of her mother and brother (both victims of an apparent shooting) over the weekend, actress Jennifer Hudson may be looking at another twist to this horrible tragedy. Over the weekend, Hudson and her family issued a $100K reward for the safe return of her seven-year-old nephew, Julian King, who's been missing since Friday night's attack.

But police are now saying they found the body of a young boy in a white SUV belonging to Hudson's deceased brother.

The story's still developing, but at this time, police have reportedly only taken one man into custody: Hudson's estranged brother-in-law, William Balfour, who previously served seven years in jail for attempted murder.
