The Winehouse family released the following statement:

    "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."

The "Rehab" singer was found dead in her London home on July 23. She was 27 years old.

The family adds, "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."
