In January, a spokesman for Southwark Coroners’ Court in London issued a statement confirming the cause of death of the Nothing Compares 2 U singer.

“This confirms that O’Connor died of natural causes,” the spokesman said.

After news of O’Connor’s death broke, London’s Metropolitan Police confirmed that her death was not being treated as suspicious.

“Police were called at 11.18am on Wednesday 26 July to reports of an unconscious woman at a residential address in SE24,” a police statement said.

Officers attended and a 56-year-old woman was pronounced dead at the scene.

“The victim’s next of kin have been informed. The death is not being treated as suspicious. A file will be prepared for submission to the coroner.”

O’Connor’s final tweet included a photo of her with Sheen, accompanied by the message: “I’ve been living as an undead nocturnal being ever since. He was the love of my life and the light of my soul.”

“We were one soul split in two. He was the only one who loved me unconditionally.

“I’m lost in the Bardo without him.”

O’Connor had three other children, Jake, Roisin, and Joshua.

Irish President Michael D. Higgins praised O’Connor’s “beautiful and unique voice”, adding that he hoped her “spirit continues to evolve”. [may] “Finding the peace she was looking for in so many different ways.”
