The Cranberries Singer Dolores O'Riordan: Cause Of Death Revealed

British authorities have ruled Dolores O'Riordan died by drowning due to alcohol intoxication. 

According to BBC News, who revealed the Cranberries frontwoman's cause of death Thursday morning (September 6), O'Riordan was discovered submerged in her hotel bathtub at London's Park Lane Hilton at the time of her death on January 15. She was 46.

"I saw Mrs O'Riordan submerged in the bath with her nose and mouth fully under the water," PC Natalie Smart told the inquest. During the hearing, it was learned that empty alcohol bottles and prescription drug containers were discovered inside the hotel room O'Riordan resided while recording for a tour slated for this year.

Per expert witnesses, the "Zombie" musician had injuries or signs of self-harm but drank an excessive amount of alcohol before dying in what coroner's are calling a "tragic accident." Toxicology tests returned the "Dreams" vocalist had only "therapeutic" amounts of medication in her blood.

The Irish singer's publicist was the first to provide a statement of O'Riordan's death in January, though the circumstances regarding her passing were not immediately made public.

In the wake of her death, The Cranberries released the following statement:

"Today we continue to struggle to come to terms with what happened. Our heartfelt condolences go out to Dolores' children and her family and our thoughts are with them today. Dolores will live on eternally in her music. To see how much of a positive impact she had on people's lives has been a source of great comfort to us. We'd like to say thank you to all of our fans for the outpouring of messages and their continued support during this very difficult time. We request, please, for our privacy to be respected at this time."

As we reported, the Limerick-born performer was set to lay down vocals for the metal band Bad Wolves' pre-approved rendition of The Cranberries' iconic hit "Zombie" before her death.

Following a three-day memorial in her honor, O'Riordan was laid to rest in Herbertstown January 23.
