Julia Hudson speaks and pleads for her son

At their church, Julia Hudson pleaded for the safe return of her 7-year-old son, Julian, on Saturday, a day after the siblings' mother and brother were found shot to death at the family home in the Englewood neighborhood.

"I don't care who you are, just let the baby go," Julia Hudson said to a crowd from the podium of the Pleasant Gift Missionary Baptist Church with the boy's father, Greg King, at her side.

"I know he's out there," she pleaded. "Just let him go. Put him on the side of the street. He'll sit there. Somebody will see him. He'll probably cry until somebody comes along."

"My greatest fear has already happened," Julia Hudson said. "My greatest hope is finding my child."

The FBI have been called in to officially assist in helping find Julian.

Julia Hudson said that her famous sister was in Chicago on Saturday, a day after she called her in hysterics. Jennifer Hudson's fiance, who answered the phone, couldn't understand Julia Hudson and handed the phone to Jennifer.

"Despite her being who she is, she is still my sister," Julia Hudson said. "She understood what I was saying. She was screaming. She flew in right away, and we've been together since. We're all still in a state of shock. I don't know nothing else to do but pray."

William Balfour's mother, Michele Balfour, said that her son had been married to Julia Hudson for several years, but that they were separated. She also said Donerson had ordered him to move out of the home last winter. Michele Balfour told reporters that she offered her condolences to the family and denied her son had any involvement.

"All I want is for my son to come home," she said.
