Amy Winehouse was drug-free when she passed away at age 27 in London on July 23.
A rep for the late "Rehab" singer's family confirmed the results of a toxicology test in a statement last month. But the singer's father, Mitch, thinks she suffered a fatal seizure related to alcohol detoxification.
The Winehouse family released a statement last month acknowledging that Amy's autopsy report showed there was alcohol present. "But it cannot be determined as yet if it played a role in her death," they added. A definitive cause of death is expected to be determined in October.
