Anna Nicole Smith's son Daniel took drugs and stole Methadone from his mother, an inquest into his death heard on Monday (17Mar08). Larry Birkhead, the father of Anna Nicole's baby daughter Dannielynn, stunned the Bahamas hearing when he revealed his former lover noticed drugs were missing from her home in Studio City, California in April 2006. And when she checked her in-home surveillance cameras, Anna Nicole had video proof that Daniel and his friends had stolen the Methadone, Birkhead testified. Birkhead also told the court he's now not completely sure he saw lawyer Howard K. Stern smoke marijuana with Daniel, despite telling police he witnessed just that in 2006. The inquest also heard that Daniel was taken to a Los Angeles hospital for misuse of valium in July 2006, reports TMZ.com. Daniel died from a suspected drug overdose three days after his mother gave birth to baby daughter Dannielynn in September 2006. He was 20. Anna Nicole passed away from an accidental overdose in Florida six months later in February 2007.
