London (CNN) A serial killer who drugged and murdered four men he met on gay dating sites has been jailed for life. Stephen Port, 41, from London, was convicted of killing Anthony Walgate, 23, Gabriel Kovari, Daniel Whitworth, 21, and Jack Taylor, 25, over a 15-month period between June 2014 and September 2015. He was also found guilty of drugging or sexually assaulting seven other victims, who survived. UK police are reviewing the chemsex-related deaths of 58 other men , previously dismissed as drug overdoses, amid fears some may be linked to Port.
