July 29, 2018

Yokohama- Police rearrested a former nurse on Saturday in a serial murder case in Yokohama, Kanagawa Prefecture.

The woman, Ayumi Kuboki, 31, poisoned Nobuo Yamaki, 88, a patient at Oguchi Hospital, now Yokohama Hajime Hospital, on Sept. 18, 2016, the Kanagawa Prefectural Police Department said.

The police had already arrested Kuboki on charges of killing another 88-year-old male patient, Sozo Nishikawa, at the hospital in the same way and sent her to prosecutors.

Kuboki admitted mixing of an antiseptic in an intravenous drip administered with Yamaki to kill him, the police said, adding she offered an apology.

Yamaki and Nishikawa had been treated in the same room.

In Nishikawa's case, the Yokohama District Public Prosecutors Office said Saturday it has put off making a decision on whether to indict her. Jiji Press
