Graham Young was only 14 years old when he was arrested for murder – and the murder in question was that of his stepmother, Molly. He had also been trying to poison his father, sister and a friend of his from school.
Young was convicted on three counts of attempted murder (the murder of his stepmother could not be verified, as she had been cremated) and served nine years in a prison for the mentally unstable. After his release, he poisoned at least another seventy-two people, two of them fatally. He was once again arrested, and this time sentenced to life in prison. He eventually died in Parkhurst prison at the age of 42.
