The most likely explanation for this phenomenon is that advertisers love to advertise to women. Remember, news is simply programming and programming is just a delivery system so that marketers can put commercials in front of the audience's eyeballs. (Hip executive types love to refer to this as "monetizing the audience". Gag me.)Anyway, so you have advertisers craving women 25-54, so you hire a bunch of women to aim news stories at those women. Voila: A surfeit of stories about cute white chicks who turn up missing, kill their husbands, or are killed by their husband. And don't forget about the surplus of stories about cute blonde teachers who have sex with prepubescent boys. This explains everything.
