A formal inquiry into the death of Anna Nicole Smith's 20-year-old son has been scheduled for March 27 in the Bahamas, the chief magistrate said Tuesday.

The reality TV star, who gave birth to a daughter three days before Daniel Smith mysteriously died at her hospital bedside on Sept. 10, will be among the witnesses required to testify before the jury inquest, Chief Magistrate Roger Gomez said.

"It's to try and answer all the unanswered questions that have been raised in this matter," he told reporters.

The inquest at the coroner's court will be open to the media, he said.

A private pathologist concluded that Daniel Smith died from a lethal combination of methadone and two antidepressants. Gomez didn't disclose the conclusions of the official pathologist or a police investigation.

Smith, 39, has said she was seeking privacy when she came to the island chain in July.
