More details are revealing themselves about what led to the tragic deaths of Jennifer Hudson's mother, brother and nephew. Reports say, in early October, suspect William Balfour accused his estranged wife Julia (Jennifer's sister) of having a boyfriend.  He threatened to harm her family if she didn't end things.  Julia brushed off the threat as he had made similar statements in the past.  A couple weeks later, when at the Hudson's house, he saw a gift that was given to Julia by her boyfriend.  He again threatened her.  And allegedly made good on his promise about an hour later.  Here's the lesson:  if someone threatens bodily harm to you or your loved ones, take it seriously.  Call the police.  Have documentation.  I don't know if it would have made a difference in this case or not.  But what if it would have?  The mother in me is just so sad about this case. />More details are revealing themselves about what led to the tragic deaths of Jennifer Hudson's mother, brother and nephew.
