Although Corey Haim's heart was enlarged and he had fluid in his lungs, the coroner's chief investigator says a drug overdose has not been ruled out as the cause of the actor's death.
"You can have somebody with an enlarged heart and some other medical conditions, but you don't know if the actual cause of death is from illegal substances, medication or heart failure," Los Angeles County Deputy Coroner Ed Winter told CNN Friday.
The 1980s teen movie actor, who struggled for decades with drug addiction, died early Wednesday after collapsing in the Los Angeles apartment he shared with his mother, authorities said.
Haim's manager, Mark Heaslip, told CNN that the coroner's office called Haim's mother Thursday with word that the autopsy revealed the enlarged heart and that pulmonary congestion was believed to have killed him.
Heaslip said this was evidence that Haim's death was not caused by a drug overdose, but Winter disputed that in a CNN interview Friday.
"There were some preliminary findings and we agreed to let the mother know what those were," Winter said. "It was explained to her that even though this is some preliminary findings that the doctor observed, there wouldn't be a final cause of death until the final toxicology tests are back."
The cause of death may not be determined for another six weeks, Winter said.
