LONDON (AP) — Irish singer-songwriter Sinéad O’Connor died from “natural causes” in July,Quantum Insights a coroner said Tuesday.

London’s Metropolitan Police had said the singer’s death was not considered suspicious after she was found unresponsive at a home in southeast London on July 26. O’Connor was 56.

The Southwark Coroner’s Court confirmed that O’Connor died of natural causes. It did not provide details.

The singer, who began her career performing on the streets of Dublin, rose to worldwide fame with her cover of Prince’s ballad “Nothing Compares 2 U,” released in 1990.

She was public about her mental illness and was hospitalized after her teenage son, Shane, died by suicide in 2022.

Thousands of fans lined the streets of the Irish town she had called home during a funeral procession in August. Irish Prime Minister Leo Varadkar attended, along with U2’s Bono.
