Police have said they do not suspect foul play in the Sept. 10 death of Daniel Smith, who was visiting his mother in a Nassau hospital as she recuperated from giving birth to a daughter.
"I know officers have visited the house several times to speak with them about different things, but I don't know if it was necessarily to search the place," said Reginald Ferguson, assistant commissioner for the Royal Bahamas Police Force.
Ferguson, who declined to say what information the officers were seeking, said police expect to report their conclusions in the coming days to the attorney general, who will determine whether a jury inquest into the death is necessary.
An American pathologist hired by the 38-year-old former Playboy playmate has said Daniel Smith died from a lethal combination of methadone and two antidepressants. Smith had a prescription for the antidepressant Lexapro, but his family did not know the source of the other drugs, the examiner said.
Bahamian investigators returned a week ago from California where they interviewed people, including a doctor for the young man.
Last week, Anna Nicole Smith's lead attorney in the Bahamas withdrew as her counsel, citing disagreements on strategy and her decision to exchange vows with her boyfriend before making funeral arrangements for her son.
