The private pathologist hired by the family, Dr. Cyril Wecht, has confirmed that the antidepressant Amitriptyline was found in Smith's body, as well as two over-the-counter cold medicines, methadone and the antidepressants Lexapro and Zoloft, People magazine reported Thursday.
People also reported that a mild over-the-counter sedative was found in the 20-year-old's system during the autopsy. He died on Sept. 10.
Wecht holds to his statement that Daniel was killed by the combination of Lexapro, Zoloft and methadone.
He said about the other medications, "The levels are insignificant and they don't mean a thing. They're of no consequence."
