Biography
For years, he had been receiving orders from someone he didn't know, on one phone. Shortly after Miracle Day he was ordered to have anybody with knowledge of Torchwood killed. He ordered Lyn Peterfield to poison Captain Jack Harkness, but Jack was given an antidote and survived. (TW: Rendition)

Rex Matheson later confronted Friedkin, and got his phone- the only way Friedkin could contact the mysterious people who knew about the miracle. Rex then shot close by Friedkin's ear, deafening him. (TW: Dead of Night)
