Dolores O'Riordan Cause Of Death Revealed

Dolores O’Riordan of Irish rock group The Cranberries accidentally drowned earlier this year, a coroner’s inquest has revealed.

O’Riordan was found in the bathtub of the Park Lane Hotel in London on Jan. 15. She was 46.

On Thursday – what would have been the singer’s 47th birthday – the Westminster Coroner’s Court heard that O’Riordan was intoxicated when she died. Her alcohol level was 330 mg per 100 ml of blood, more than four times the legal limit for driving.

Five empty bottles of alcohol from the room’s mini-bar were found as well as a bottle of champagne.

“There’s no evidence that this was anything other than an accident,” coroner Dr. Shirley Radcliffe said. “There was no intention, this seems to be solely a tragic accident.”

The inquest also found evidence that O’Riordan had been smoking heavily and using prescription drugs to treat anxiety. Among them was Lorazepam, which the singer had been combining with alcohol when she wrote a suicide note four months earlier, according to a psychiatrist quoted at the inquest.

In 2012, singer Whitney Houston was found submerged in a hotel bathtub in Beverly Hills. Her death was ruled an accidental drowning. She had cocaine, cannabis and several prescription drugs in her system at the time of her death.

O’Riordan married Canadian-born Don Burton in 1994 and lived off-and-on in Buckhorn, just north of Peterborough, Ont. until 2013 when their marriage ended and she returned to Ireland. O’Riordan had three children: Taylor Baxter (who was born in Toronto), Molly Leigh and Dakota Rain.
