While many initially thought she took her own life, aligning with her well-documented mental health battles, it appears that the London coroner's office has determined her demise to be of natural causes.

Best known for ‘80s and ‘90s pop hits such as her rendition of “Nothing Compares 2 U,” O’Connor was famous around the world for also speaking out about mental health, abortion and protesting the sexual abuse in the Catholic Church. Her death at age 56 came a little more than a year after her son, Shane, died by suicide in early 2022 - a tragedy that led to the singer being hospitalized after she threatened self harm.
It’s still unclear how O’Connor died, but Tuesday’s coroner’s ruling excludes some of the most widely feared possibilities.
André Rebello, secretary for the Coroners’ Society of England and Wales, explained that “all deaths by suicide are ‘unnatural.’ Most deaths from natural causes are not reported to any coroner but if a coroner found natural causes it would never be a suicide.”
If someone dies from ‘natural causes,’ this means that they did not die by suicide, or in an accident, or by a drug overdose, he said. Rebello stressed that he was talking generally, and not about any specific case.
The Southwark Coroner’s Court said it had no further comments about O’Connor’s death.
This is definitely a surprising development and really deepens the mystery surrounding Sinead's untimely death.
