Graham Young - serial poisoner is Japanese teen killer’s idol

A Japanese schoolgirl who is alleged to have poisoned her 47-year-old mother, and who kept an Internet blog diary of her crime, has been arrested, following a tip-off to police by her brother. During last summer, the 16-year-old, from rural Shizuoka, central Japan, was apparently inspired by Graham Young, the notorious ‘Teacup Poisoner’ of Bovingdon, Hertfordshire, who, in 1962, aged 44, slowly killed his stepmother with what was thought to be the same lethal substance used by the girl – lacing her mother’s food with increasing doses of thallium, a potent rat poison.
