William Balfour, the 31-year-old former brother-in-law of Oscar winner Jennifer Hudson, was found guilty of murdering Hudson’s mother, brother, and 7-year-old nephew. The jury took three days of deliberations to reach a guilty verdict, and Balfour now faces a mandatory life sentence in jail.

Balfour had been married to but separated from Hudson’s sister, Julia, at the time of the shootings, and the prosecution tried to prove that he had threatened to kill the Hudson family dozens of times while attempting to reconcile with her. “He said, ‘If you leave me, you will be the last to die.
