I've not seen anything in this, apols if it's already been done:

Robert Trigg has been jailed finally for murdering two partners because their parents paid for someone to investigate. This man had a long history of domestic violence towards the women he killed and other partners too. How can the police have thought both deaths were natural/ misadventure? Those poor women and their poor families. He was practically wearing a t shirt saying 'I did it!', how on earth did he get away with it for so long?!
