Daniel Smith was found sitting upright in a chair in his mother's room at the private Doctors Hospital in the Bahamian capital of Nassau early on Sunday and could not be revived, police said. There were no signs of trauma on his body and no sign of a struggle in the room, police said.

Daniel had flown to Nassau on Saturday to see his 38-year-old mother, who had checked into the hospital under an assumed name and delivered a healthy baby girl by Caesarean section on Thursday.

An autopsy was being performed at nearby Prince Margaret Hospital, according to assistant police commissioner Reginald Ferguson. He said police had not ruled out any cause of death and were still awaiting the pathologist's report.

"It would not be wise for police to try and come to a conclusion before we have a proper investigation," Ferguson said.

Smith's lawyer, Howard K. Stern, said he did not believe drugs or alcohol were a factor.

"Anna Nicole is absolutely devastated by the loss of her son. He was her pride and joy and an amazing human being," Stern said in a news release.
