Colin Fishwick Colin Michael Fishwick was a teacher and old colleague of John Stape ' s . In 2010 , John " borrowed " Colin ' s identity so that he could teach , as he had left the profession in disgrace after having an affair with pupil Rosie Webster and later kidnapping her . Using Colin ' s name set in motion a sequence of events which led to John ' s downfall and Colin ' s death . Colin ' s parents were John and Joy Fishwick . He was born two weeks late and had claustrophobia later in life . When looking back on Colin ' s life , Joy would later recall that Colin had no friends in school and that he was closest to her , but that this changed when he graduated with an Honours degree in teaching and that by 2010 he was barely in contact with her . According to neighbour Clifford , Colin was a terrible son who would probably only regain contact to collect his inheritance in the event of Joy ' s death . Colin ' s love life was equally disastrous . He had an affair with a woman whose husband , Ben Fielding , was in prison for assaulting a policeman . When he heard in April 2010 that Ben was about to be released , Colin , fearing that Ben would hunt him down , immediately made plans to uproot and move to Canada , explaining to friends that he wanted a fresh start as he hated his job . At a leaving party , Colin met up with his old colleague John Stape and enjoyed sticking the knife in over John not being able to get a teaching job because of his past . Unbeknown to Colin , John stole some documents from his office and used his identity to apply for a teaching position at Daisyfield High School . In July , Colin returned to the UK , having apparently had a change of heart . He told Charlotte Hoyle about his plans to return and Charlotte in turn warned John , as she was in on his secret . On his return , Colin got a job at a bookshop but really wanted to teach again . He was surprised when John and Charlotte met with him to break the news about John using his identity . Colin , however , agreed not to go to the police . A few days later he was approached by Ben Fielding , who had been told where to find him by Fiz , as she thought Ben was going to batter John thinking he was Colin . Colin received a severe beating and decided to be harder on John , blackmailing him for £2 , 000 in exchange for him returning to Canada . When he arrived to collect his money , Colin was met by Charlotte and John and only £500 . He was about to go to the police but suddenly fell to the floor , dead . Realising that the police would think he murdered Colin to cover his tracks , John got Charlotte to help him move the body to the building site at Underworld while they decided what to do next . Before John returned to retrieve the corpse , it was buried under a load of cement , and the factory became Colin ' s grave . Almost a year later , in May 2011 , drainage problems on the factory side of the Street resulted in the foundations of the factory being dug up . Still living at No . 5 , John realised that Colin ' s body would be discovered and joined Owen Armstrong ' s digging crew . Working late , he unearthed the body himself and dumped it in the canal . Fiz had found him with the body but had reluctantly agreed to help him dispose of it as she had committed fraud by using Colin ' s bank account , accessing money " Colin " had inherited after Joy ' s death in January of that year , by pretending to be Colin ' s wife . ( John had befriended Joy in her final days and smothered her after confessing to Colin and Charlotte ' s murders . ) It was later found out that John had buried Colin ' s body and Fiz was put on remand , accused of Colin ' s murder , as well as Charlotte and Joy ' s deaths . Although technically , John did not kill Colin , the beatings caused by Ben Fielding ( who hasn ' t been linked to Colin ) made it look like John must have done it himself to cover his tracks . " Colin made another " appearance " in June 2011 wrapped up in the carpet , with his feet shown and a decomposing hand also briefly appearing . " List of appearances . 2010
