The coroner who examined Anna Nicole Smith's son, Daniel, after he suddenly died on Sunday, tells the New York Daily News, "We have a cause of death, but I am reserving it pending complete toxicology reports," suggesting that drugs may have figured into the 20-year-old's passing. "It was not natural causes," adds the coroner. "[And a] heart attack was ruled out." Though unconfirmed, one newspaper from Nassau, Bahamas, where Daniel Smith died just days after meeting his newborn sister, has alleged that "various medications, along with drugs," were found in his system.
