Sidney Cooke , born 18.4.1927, nicknamed Hissing Sid, was imprisoned for the manslaughter of Jason Swift and received a 19 years sentence in May 1989. On 30th November 1985 Jason Swift’s body was discovered by a farm worker in Stapleford Tawney, Essex. It was thought that Jason was probably killed on 14th November 1985 and asphyxia was the cause of death, probably as a result of suffocation. Jason’s family home was in Hackney, but it is said by a former Islington residential worker that Jason was in Conewood Street children’s home not long before he was killed and ISN survivors remember him well. In the 90s Eileen Fairweather, journalist, heard from two separate sources about Jason being in Conewood Street but wrote that because of missing files Islington Council could not confirm this. Her article is here.
A timeline of the investigation, named Operation Stranger and Operation Orchid is available here.
Cooke’s sentence was reduced to 16 years on appeal in 1989 and he gained parole in 1998. On January 26th 1999, he was again arrested and charged with committing 18 sex offences between 1972 and 1981. On 17th December 1999 he received two life sentences.
