The Huffington Post reported this a few days back: Brazilian police suspected in the killing of gays. The brief report states a sergeant may be involved in some way in the killing of 13 gay men in Sao Paulo. Today the AFP has put out a brief news clip saying that the State Police now believe it's a serial killer and make no mention of the original suspected officer.
I'm not sure what this world is coming to if it took 13 victims before the cops realized something wasn't right. That or they just didn't care very much. Either way it's wrong and something should be done.
