NEW YORK (AP) -- Amy Winehouse's father says he thinks she died after suffering a seizure related to alcohol detoxification and "there was nobody there to rescue her."
The soul diva was found dead in her London home July 23. She had fought drug and alcohol problems for years.
Toxicology reports say there was alcohol in her bloodstream, but it was unclear whether this contributed to her death.

The singer was 27 years old.
Mitch Winehouse said Friday in a taping of Anderson Cooper's new syndicated talk show that his daughter had been off drugs for two-and-a-half years and was fighting alcohol problems, with occasional seizures.
