In December previous year, while the investigation into the mysterious deaths at the hospital was was ongoing, Kuboki told Japanese newspaper Asahi Shimbun, "I've worked hard to help patients die in peace, so I was shocked by the incidents".
A Japanese nurse is accused of tampering with the medical devices of dozens of near-death patients in order to kill them while she was off duty - all so she could avoid delivering the news to the patients' grieving families.

She claimed she only targeted seriously ill patients who she believed were going to die on her shift, but sources said some of the victims were not in serious condition when they died. The men, who'd shared a hospital room, died within two days of each other.
Kubo told investigators she did not like the responsibility of telling a patient's family a loved one had passed away.
Police believe that she deliberately contaminated the patients' intravenous drips with a disinfectant containing benzalkonium chloride, killing the first two victims in a matter of just hours.
The chemical, an antibacterial that's readily available within hospitals, was found in Yamaki's body and his IV bag.

In his case, Kuboki allegedly sneaked into his room between 3 p.m. and 4:55 p.m. September 18, 2016, ahead of her 5 p.m. night shift.
"She was the kind of person who was hard to figure out what she was really thinking, but she was considered competent", a worker said. At least 48 patients died at the hospital in suspicious circumstances over a three-month period in 2016, Japanese newspaper Asahi Shimbun reported.
Kuboki has admitted to killing "at least 20 elderly patients" in her time at Oguchi. The newspaper quoted Kuboki's mother, who said her daughter was scared of working in the hospital at night and wanted to leave her job.
