Nikki Catsouras, the 18-year-old woman, was killed in a car crash. The bloody photos of her body and the crash scene were posted on the Web for the world to see, raising all sorts of questions about privacy online. Nikki’s parents found out about their daughter’s accident just moments after it happened. But they were forbidden by the police from seeing their daughter’s body—it was simply too terrible for a parent to see. A few days later, however, Nikki’s mother saw pictures of her daughter’s crushed body while searching for an online article about the crash. The Catsouras family sued the California police for giving the pictures away to harm their privacy and they got the court’s support. But with the law on their side, the online-picture incident caused the Catsouras family a lot of pains. They had to borrow money to cover the cost of their legal fees. They forbade Nikki’s three younger sisters from using social networking sites. The next challenge for the family will be this: How can they stop the spread of the remaining photos present on the Web? In the meantime, the Catsouras family feel better to know that they are one step closer to the end of a seemingly endless nightmare. "In a perfect world, I would push a button and delete every one of the images," says Nikki’s mother, "but it feels good knowing that at least now, at least in California, our case will help prevent this from happening to anybody else."
