Was it a sex game gone horribly wrong? That's what Italy's supreme court wants to figure out.
The court explained its reasoning to retry Amanda Knox and her former boyfriend with the 2007 murder of her British roommate Meredith Kercher.
Knox was acquitted by an appeals court in 2011, but Italy's high court overturned the ruling and says the jury didn't consider all the evidence, including the prosecution's initial theory that Kercher was killed during a twisted sex game. A new trial could start as early as this fall.
