Bahamas police officers investigating the death of Anna Nicole Smith's 20-year-old son recently traveled to California, where they interviewed people including a doctor for Daniel Smith, an officer said Monday.
The four officers, who returned from the U.S. on Sunday, were seeking information about the days before Smith arrived in Bahamian capital of Nassau, where he died Sept. 10 in the hospital where his reality TV star mother had given birth three days earlier.
"We don't have any information to cause us to change our statement that no criminality was involved," Reginald Ferguson, assistant commissioner for the Royal Bahamas Police Force, told The Associated Press late Monday.
Ferguson said the officers interviewed a doctor for Smith, who died from a lethal combination of methadone and two antidepressants, according to a doctor who conducted a private autopsy. Smith had a prescription for Lexapro, but his family did not know the source of the other drugs, the doctor said.
Ferguson declined to say who else the Bahamian officers spoke with or how long they spent in California.
"They went to make inquiries relevant to the case, speaking to physicians and whomever else," he said.
"You're looking for anything you can find that can be evaluated as part of the evidence," he said. "You don't look for anything particular, you go to uncover what might have taken place."
Ferguson said the officers received assistance from local law enforcement authorities in California, but he declined to identify them.
Smith boarded a flight in California to visit his mother and newborn half-sister, arriving in Nassau the night of Sept. 9. Police had been interested in speaking with anybody who sat beside him on a plane, Ferguson said.
Ferguson said police expected to complete their investigation soon, possibly as early as this week, before submitting a report to authorities who will determine whether a jury inquest into the death is necessary, reports AP.
Smith's body is being held by a Nassau funeral home awaiting instructions from the family on burial arrangements.
