Ex-nurse claims to have killed 20 patientsWorld | 12 Jul 2018
A former nurse who allegedly killed as many as 20 elderly patients by injecting their intravenous drips with chemicals is in police custody, Japanese media have reported.
Police said yesterday that Ayumi Kuboki, 31, was in custody over the alleged murder of an 88-year-old man at a hospital in suburban Tokyo.
She was arrested on Saturday over the alleged murder of the elderly patient in 2016, but she has told police she may have killed up to 20 people, local media said.
It is believed the suspect has not worked as a nurse since the 2016 death.
Kuboki allegedly killed the 88-year-old man by injecting a disinfectant into his drip, it was reported.
The suspect has told police she mixed disinfectant into the intravenous drips of around 20 patients, Jiji Press reported, citing an unnamed police source. Kuboki reportedly said she found it difficult to deal with deaths on her shift, and injecting the drips allowed her to control when her patients died.
Jiji reported that after the 2016 murder, police found surfactant - a chemical used for products including detergent and cosmetics - in 50 unused bags for intravenous drips at the hospital.
