Amy Winehouse died trying to save her own life.

That would be the argument of her father, Mitch Winehouse, who continues to make the case that withdrawal killed Amy, not a major drug overdose that many suspected for obvious reasons. The singer passed away in July at age 27.

Why is Mitch so certain this happened?

"Everything Amy did, she did to excess," he says on Anderson Cooper's new show Anderson, debuting tomorrow. "She drank to excess and did detox to excess."

It is true that no illegal drugs were found in his daughter's system.

However, Mitch believes his daughter likely suffered an overdose from a very powerful anti-anxiety drug and later suffered a fatal seizure during detox.

According to the singer's father, she was trying to get clean once and for all. Sadly, the rampant addictions she battled for years left her too weak.

The final cause of death is still pending an official inquest.
