Daniel Smith, son of Anna Nicole Smith, died of irregular heart beat

Early reports from pathologist Cyril Wecht, the man hired by Anna Nicole Smith to look into her son’s death, indicated that the 20-year-old died of an irregular heart beat caused by a combination of drugs.

The combination of methadone, Zoloft and Lexapro caused Daniel to go into cardiac dysrhythmia. There has been no word on whether Daniel had been prescribed the drugs involved but it would appear unlikely that a doctor would knowingly recommend all three.
