The soul singer Amy Winehouse, who passed away on July 23 at her London home at age of 27, died from over-drinking, a British coroner ruled Wednesday. Oct. 26. The alcohol in the singer's system was found five times of drunk driving limit.

According to the coroner Suzanne Greenaway, Winehouse had consumed too much alcohol after weeks of abstinence, which led to death by misadventure.

The unintended consequence of such potentially fatal levels (of alcohol) was her sudden and unexpected death, Greenaway said.

Likewise, the pathologist Suhail Baithun also concluded the singer's death cause as drinking a very large quantity of alcohol, after examined her blood and urine samples, which indicated that the level of alcohol in her blood was 416 milligrams per 100 milliliters. However, the British legal limit to drive is 80 milligrams of alcohol.

Baithun said such amount of alcohol could have stopped her breathing and sent her into a coma.

Police found three empty vodka bottles, two large and one small, in Winehouse's bedroom after she died.

The star had fought publicly with drug and alcohol problems for years. Winehouse's private GP Dr. Christina Romete described the singer as intelligent and determined during the inquest. She’s made tremendous efforts over the years, Romete said.

After she successfully kicked a drug habit in 2008, drink became a problem for her. The star had been warned of the dangers of continued alcohol abuse, then she decided for abstinence.

Winehouse tried hard to abstain from drinking with the help of medication Librium to cope with alcohol withdrawal and anxiety. However, she resumed drinking prior her death.

Winehouse family released a statement, saying it is some relief to finally find out what happened to Amy.

We understand there was alcohol in her system when she passed away, it is likely a build-up of alcohol in her system over a number of days. The court heard that Amy was battling hard to conquer her problems with alcohol and it is a source of great pain to us that she could not win in time. She had started drinking again that week after a period of abstinence, the statement said.

It underlines how important our work with the Amy Winehouse Foundation is to us, to help as many young people and children as we can in her name. they added.

It means a lot to us and from the overwhelming messages of support we have had since Amy died, we know she meant a great deal to people all over the world. We want to thank everyone for that and for their continuing enthusiasm for the Foundation.
