Stephen Port, Serial Killer

It was September 14th 2015 when Jack Taylor, a 25 year old gay man was found dead in St Margaret's church in East London. 'If that's where Jack's been found, someone's put him there,' said Jack's sister, Jen. 'The Police could have put a stop to it, and Jack would still have been here.'
Three previous murders had been committed in 2014. In each case, a body was found within a short distance of the others – sometimes in the exact same spot. Yet police assumed there was no connection between the crimes. It was only after the discovery of Jack's body that investigators realised they had a serial killer on their hands.  
Earlier that month, Jack made contact with the man who would go on to poison him on the gay dating site, Grindr. That person was Stephen Port, a forty year old Chef who lived in Barking, East London.
