I have been thinking about the case of the two young missionaries who were killed, shot in the head, while they slept on a California beach in 2004. Apparently just a ramdom killing for an unknown reason. As far as I know the killer has never been caught. Then there were the ramdom people killed by Lee Malvo and John Muhammed. Or those killed by the Son of Sam killer or the Zodiac. I am sure there are other cases like this but a random killing can occur simply because someone was in the wrong place at the wrong time when someone evil had killing on his mind. Someone who was very angry at the world and took it out on strangers. I think this could have happened with Taylor and Skyla. Because there hasn't been a killing spree doesn't mean a lot because sometimes there was a longer time period between killings.
