JOHNSTOWN, Colorado (AP) -- Two teens have been charged with killing the 7-year-old sister of one of them by beating her with imitations of moves from the "Mortal Kombat" video game, prosecutors said. http://www.cnn.com/2007/US/law/12/20/mortal.kombat.ap/index.html Her own sister and her sisters boyfriend did this. I do let my 9 year old son play mortal combat but he understands it is just a game and not real and we do not play like that. My daughter who is 3 does not understand so we do not let her watch it. This is just horrible, killers are getting younger and younger.
