One of the most disgusting serial killers in American history is standing trial in Philadelphia at the moment – and, since it’s happening in the US, where reporting restrictions are light, the media are free to discuss his case. Only they haven’t – at least, not until recently, and even when the crimes are reported, they haven’t merited many headlines. Which is horrifying, when you consider what the killer is accused of. I’m going to leave out the nastiest details – but, seriously, if you don’t want to feel sick to your stomach, look away now.
