Sinéad O’Connor Cause Of Death Revealed

Sinéad O’Connor died of natural causes, British authorities announced Tuesday.

A rep for London’s Southwark Coroner’s Court tells TMZ … she passed away from “natural causes” and “the coroner has therefore ceased their involvement in her death.”

As we reported, cops in London responded to a report of an unresponsive woman at a residence … arriving to find the 56-year-old singer already dead. Attempts were made to revive her, but they were unsuccessful.

Sinéad’s 17-year-old son, Shane, died by suicide in early 2022 just 2 days after going missing from the hospital while on suicide watch. After his death, Sinéad called her son “the very light of my life” … begging for him to be at peace.

She expressed more grief about Shane less than 2 weeks before her death, saying on social media, “He was the only person who ever loved me unconditionally. I am lost in the bardo without him.”

Sinéad has also struggled with her mental health in the past, telling Dr. Phil in 2017 she’d attempted suicide 8 times in a year. She also was reported missing the year before, allegedly threatening to jump off a bridge — but Sinéad was found safe and said the suicide claims were BS.

The singer’s seen a ton of love from the community since her death … including from Conor McGregor, who had her sing during his 2015 walkout at UFC 189 in Las Vegas. He told TMZ, “The world has lost a beautiful voice and an even more beautiful person.”
