Private Pathologist: Daniel Smith Died from Lethal Combination of Drugs

SAN JUAN, Puerto Rico (AP) - Anna Nicole Smith's 20-year-old son died from a lethal combination of methadone and two antidepressant drugs, the U.S.-based pathologist who conducted a private autopsy said Wednesday.

Toxicology tests showed Daniel Smith had methadone, Zoloft and Lexapro in his system when he died Sept. 10 in a hospital room in the Bahamas where his mother was recuperating from giving birth to a daughter, according to Cyril Wecht. Methadone is used to treat heroin addiction.

"The fact that we have these drugs and the levels of the drugs overwhelmingly and most logically point to this being a tragic, accidental, drug-related death," Wecht told The Associated Press from his home near Pittsburgh.
