Julia Hudson, the 31-year-old sister of Academy Award-winning actress Jennifer Hudson, plead for the return of her 7-year-old son during a press conference at the family’s church in Chicago on Saturday.

Julia’s son, Julian King, went missing on Friday, the same day that her mother and brother were found shot to death at the family’s home on the city’s South Side.

William Balfour, Julia’s estranged husband, is a suspect in kidnapping and family slayings. He is currently in police custody.
