John Winters

John Winters was an alien possessed American scientist who was based in Cardiff in 2008. He was head of the New Eden research lab and was responsible for making the DNA used for the invasion by infecting humans with it. This DNA was implanted into the human body by his wife Laura who was a cosmetic surgeon, also alien possessed. Winters planned to use ultra-sonic soundwaves to activate the DNA and start the invasion by using the radio station of disguised alien Abigail Crowe. Winters was detained after Crowe's death, it is not known whether he was freed from his alien possession. (Torchwood Mission Game).
