Sinead O’Connor’s exact cause of death finally revealed

Her husband, John Reynolds, officially registered her cause of death in Lambeth, London. According to her death certificate, O’Connor’s passing was due to the exacerbation of chronic obstructive pulmonary disease and bronchial asthma, along with a lower respiratory tract infection.

When the London Metropolitan Police arrived at O’Connor’s apartment in Southeast London on July 26, 2023, they confirmed that her death was not suspicious. The legendary singer, known for her iconic song “Nothing Compares 2 U,” left behind three children, Jake, Roisin, and Yeshua. Tragically, her son Shane had taken his own life in 2022 at the age of 17.

In her final heartfelt post on X, O’Connor described Shane as “the only person who ever loved me unconditionally.” Throughout her career, O’Connor was known for her powerful vocals and her distinctive close-cropped haircut. She was also recognized for her outspoken political views, which often caused controversy.

One unforgettable moment was O’Connor’s infamous 1992 “Saturday Night Live” appearance, where she tore up a photo of Pope John Paul II on live TV. This action sparked widespread condemnation and boycotts, making headlines around the world. Despite the controversy, O’Connor’s talent and unique voice will continue to be remembered by fans worldwide.
