A former nurse in Chiba Prefecture, Japan, is now formally facing a murder charge after prosecutors allege she used a syringe to inject feces into a hospitalized patient's IV line during an overnight shift — and that she had searched online beforehand whether doing so could kill him.
The Chiba District Public Prosecutors Office indicted Miyuki Furukawa, 51, on August 4, 2026, on a charge of murdering 75-year-old patient Eiji Aita. Police allege that at around 3:55 a.m. on January 30, 2026, Furukawa injected excrement — which investigators believe she obtained from a waste disposal room inside the hospital — directly into Aita's intravenous tube using a syringe. Aita died of multiple organ failure at around 10:30 p.m. the following day, roughly 19 hours later.
A hospital worker reported the death as suspicious to police on February 1, 2026, more than a week after Aita died. Investigators say security camera footage and other evidence identified Furukawa as a suspect; she was arrested in mid-July 2026, nearly six months after the incident. Investigative sources told Japanese outlets that a search of Furukawa's smartphone showed she had researched online whether injecting feces into a person's bloodstream could be fatal, before the incident occurred. Furukawa has denied the allegation.
A case that traveled fast among nurses
Stories like this one spread through nursing social media and group chats faster than almost any other kind of headline, and it isn't hard to see why. An IV line is one of the most basic forms of trust in a hospital — a patient assumes that whatever's going into that tube has been checked, verified, and belongs there. When a case like this surfaces, even one that happened on the other side of the world, it lands as a direct hit on that assumption, which is exactly why nurses everywhere have been talking about it.
I want to be very clear about something first: this is an extreme, rare outlier. The overwhelming majority of nurses would never come close to something like this, and it says nothing about the profession as a whole. But it is a real reminder about access. Most of us work in facilities where, once you're badged in, you have a lot of unsupervised trust around medication rooms, waste disposal, and patient lines — because that trust is what makes bedside nursing functional. What jumps out to me here isn't just the act itself, it's that it reportedly took a coworker more than a week to flag a death as suspicious enough to call police. That gap is its own systems failure, and it's worth every facility asking itself honestly: would we catch this faster, or slower?
What comes next
Furukawa remains in custody and now faces a formal murder trial in Japan's court system following the August 4 indictment. No trial date had been publicly reported as of this writing, and she has denied the allegation through her legal representation. As with any pending criminal case, she is presumed innocent unless and until a court finds otherwise.
