Sinéad O’Connor passed away at the age of 56 on July 26, 2023, in London, just 18 months after the tragic suicide of her 17-year-old son, Shane Lunny.

The cause of her death was determined to be complications from chronic obstructive pulmonary disease, bronchial asthma, and a respiratory tract infection.

Her family announced her passing, expressing devastation and requesting privacy during this difficult time.

O’Connor had expressed profound grief over Shane's death, describing him as the love of her life in a heartfelt social media post.

Her ex-husband, John Reynolds, who was married to her from 1987 to 1991, was named the executor of her estate.

In her will, O’Connor left an estate valued at £1.7 million to her children, which was reduced to £1.4 million after debts and expenses.

She designated her son Shane to inherit her religious regalia, while her youngest son, Yeshua Bonadio, was to receive her guitar collection.

Despite announcing her retirement from music in 2003, O’Connor continued to create new material, with her last album released in 2014.

Before her death, she was preparing to release her 11th studio album and had plans for a 2024 tour and a film adaptation of her memoir 'Rememberings'.

O’Connor was a vocal critic of the Catholic Church and was ordained as a Latin Tridentine priest in 1999.

Reports about O’Connor's British estate are still pending, and the coroner confirmed her death was due to natural causes.

Her last tweet reflected her deep sorrow over her son's death, highlighting the emotional toll of losing a child.
