An autopsy has found that Dolores O’Riordan, the lead singer of the Cranberries, drowned in a hotel room bathtub.

Page Six reports that a medical examination found that the Irish singer’s death was accidental and a result of alcohol intoxication.

A blood test reportedly found that O’Riordan’s blood-alcohol content was four times the legal limit at the time of her death at age 46. She was found dead on January 15 at the Park Lane Hilton hotel in London.

“There’s no evidence that this was anything other than an accident,” the coroner, Dr Shirley Radcliffe, told the Guardian.

“There was no intention, this seems to be solely a tragic accident.”

O’Riordan had been staying at the hotel during a recording trip ahead of a planned tour.
