Sinead O’Connor‘s official cause of death has been revealed one year after her passing. The death certificate indicates her. The death certificate indicates that her passing was due to "exacerbation of chronic obstructive pulmonary disease and bronchial asthma together with low-grade lower respiratory tract infection." Registered by her husband, John Reynolds, in London on July 24, the certificate states O’Connor died at 56 in her London home on July 26, 2023. Authorities found her "unresponsive" and later confirmed her death was not suspicious, with the investigation handed to the coroner. London’s Southwark Coroners Court determined O’Connor died of natural causes and ceased their involvement.

O’Connor’s family expressed deep sorrow at her passing, requesting privacy during this difficult time. The Irish singer, who battled mental illness, lost her 17-year-old son Shane to suicide in 2022. She is survived by three children, including her 28-year-old daughter, Roisin Waters.

O’Connor’s debut album, The Lion and the Cobra (1987), featured hits like “Mandinka” and “I Want Your (Hands On Me).” Her 1990 album, I Do Not Want What I Haven’t Got, included the global hit “Nothing Compares 2 U,” and other favorites like “The Emperor’s New Clothes” and “I Am Stretched on Your Grave.”
