AceShowbiz - Tragic actor Corey Haim died of natural causes, according to findings by Los Angeles Coroners officials. Reports suggested "The Lost Boys" star died of a drug overdose in March, but a full toxicology investigation has ruled the narcotics in the star's system at the time of his death did not kill him.

Instead, a bad heart and pneumonia caused the tragedy, along with a blood flow issue. Haim's longtime pal Corey Feldman suggested natural causes when he spoke out about his friend's death a day after he was pronounced dead at a Burbank, California hospital. Feldman insisted Haim may have suffered kidney or heart failure.

He told U.S. talk show host Larry King, "They (media) need to stop saying it's a drug overdose. They need to stop saying, you know, their theories of what they think it is or isn't, because, at the end of the day, until the coroner's report comes out, until we have specific evidence, until we know exactly what the toxicology reports say, nobody knows. And nobody is going to know."

"We all are aware of the fact that Corey Haim has had a long and detailed drug history... However, most recently, he's been, honestly, in the best frame of mind that he's ever been in in the past year. I would say with his mom battling cancer, he's really showed up. He's really become a man. He's been there. He's been there for her, taking care of her, being responsible."

And Feldman offered his own alternative theories to his friend's tragic death, fearing it may have been a result of new medication he was prescribed shortly before his death. He added, "I know that there were symptoms that he was showing that expressed it could be a number of things. You know, this could have been a kidney failure. This could have been a heart failure. This could have been a mixture of drugs, it could have been a cocktail that's specific or it could also have been the fact that your body shuts down after years of abuse..."

"I know that he was recently seeing a treatment specialist who was new in the mix, who he had only been seeing for the past two weeks. And that treatment specialist put him on a new line of medications, which were special medications. I'm not going to go into what they were, but let's just say that they may not have corresponded properly with the medications that he was currently taking."
