Sinead O’Connor Died of Natural Causes, Coroner Says

A London coroner’s office said Tuesday that the Irish singer Sinead O’Connor died from natural causes.

Ms. O’Connor, 56, was found dead at a residential property in London in July. Shortly afterward, the local coroner announced they would conduct an autopsy of her body.

In a brief statement on Tuesday, the coroner said that “Ms. O’Connor died of natural causes.” The coroner said they had “therefore ceased their involvement in her death.”

Best known for her rendition of Prince’s “Nothing Compares 2 U,” Ms. O’Connor became a global star in the 1990s — not just for her music, but for her political provocations, on- and offstage. Most memorably, Ms. O’Connor tore up a picture of Pope John Paul II during a 1992 “Saturday Night Live” performance to protest child sexual abuse in the Roman Catholic Church.

In an appraisal of Ms. O’Connor’s career for The New York Times, the pop critic Jon Caramanica said the singer “was something grander than a simple pop star.”

She “was a fervent moralist, an uncompromised voice of social progress and someone who found stardom, and its sandpapered and glossed boundaries, to be a kind of sickness,” Mr. Caramanica wrote. “She was also a singer of ferocious gifts,” he added.
