The man on trial for killing singer Jennifer Hudson's mother, brother, and nephew was declared guilty on all seven charges Friday. William Balfour, the former husband of her sister Julia, had repeatedly threatened the family before the 2008 murders. The Oscar-winning actress was the first to testify in the trial, saying, "None of us wanted her to marry him." According to tweets from Chicago Tribune reporter Stacy St. Clair, Hudson wept after the verdict was read. Balfour's defense attorney has said he'll appeal the decision.
