Molly Cuddihy, 23, died on Tuesday at the Queen Elizabeth University Hospital (QEUH) in Glasgow. She had previously described to the Scottish Hospitals Inquiry how she developed septic shock while being treated there for a rare cancer.

The Crown Office has confirmed that it is now investigating. A spokesman said: “The procurator fiscal has received a report on the death of a 23-year-old woman in Glasgow on August 26, 2025.

“This report was made by a doctor, as they must where guidance requires them to do so.

“The procurator fiscal is examining the circumstances of this death and significant developments will be shared with the family during this process.”

NHS Greater Glasgow and Clyde said: “Our deepest condolences are with the family of Molly Cuddihy during this extremely difficult time. To respect patient confidentiality we are unable to provide further comment.”

The Scottish Hospitals Inquiry is examining the construction of the QEUH campus, which includes the Royal Hospital for Children, following deaths linked to infection, including that of 10-year-old Milly Main.

Ms Cuddihy, who was diagnosed with metastatic Ewing’s sarcoma at 15, gave evidence to the inquiry in 2021. She told how, while being treated between January 2018 and 2020, she suffered “frightening” fits caused by a hospital-acquired infection.

Not long after beginning chemotherapy, her body went into septic shock. She was diagnosed with mycobacterium chelonae, an infection in her treatment line that she later learned came from the hospital environment.

She recalled being prescribed a “very strong” antibiotic she compared to bleach. “The medication had horrible side effects. I thought chemo was bad, but this was something else,” she said. “I got a prolonged QT interval with my heart. This is when my heart pumps out the blood, but then doesn’t fill up fast enough, so I would often collapse.”

Ms Cuddihy told the inquiry that medical staff were just as much in the dark as she was about the source of the infection. “I was made sicker by the environment,” she said.

Alongside her treatment, she devoted time to supporting other young patients, podcasting and fundraising, helping to raise hundreds of thousands of pounds for the hospital.

In a statement, her family said: “It is with broken hearts that we share the passing of our beloved daughter Molly. She was a special soul who brought light, love, and kindness into the lives of so many around her.

“What we will always treasure is the way she touched others, often without ever realising just how truly extraordinary she was.

They added: “We are devastated by her loss and struggling to comprehend a world without her gentle presence. To us, she will forever be our precious girl: deeply loved, irreplaceable, and always remembered.”
