How did Bella Thorne's dad die? Bella's dad died in a car crash in 2007. How did Naruto mom and dad die? His mom died because she was kidnapped by Tobi (who had threatened to kill naruto first) and had the kyuubi inside of her (the nine tails) taken out of her.
Of course we'll know afterwards why Kakashi had to kill her, but the thing to know now is in that particular moment Tobi (the evil Obito) was born. This was the moment that caused all of the upcoming events in the history of Naruto's world.
