The mother of actor Corey Haim confirmed to Access Hollywood Thursday that the 38-year-old former child star died of pulmonary congestion. Judy Haim — who has spent the last year battling breast cancer — told the newsmagazine she received an early courtesy call from the Los Angeles County Coroner’s Office today and was told that a preliminary autopsy revealed that Corey had an enlarged heart, causing his lungs to fill with water and leading to his death in the family’s L.A. apartment early Wednesday morning.
