London, Oct 21 (IANS) Singer Lisa Marie Presley believes she could have helped save ex-husband Michael Jackson's life and says she is still haunted by his death.

In an interview to Oprah Winfrey, Presley said she could have helped Jackson turn his life around if she had known the King of Pop was so ill, reports contactmusic.com.

"I know that it's naive to think that I could have (saved him) but I wanted to. Had I made a call, had I stopped being so shut off from him, had I just said, 'How are you?' I really regret that I didn't," she said.

However, Presley, who was married to the pop superstar from 1994 to 1996, fears that he would have refused her aid even if she had reached out to help him. She said she knew the superstar was charting a course to destruction while she was married to him.

She added, "I think that was a train headed in a certain direction that I don't know if anyone could have stopped and I've had to really get my head around that in order to stop the pain."
