Anna Nicole Smith did not appear to be a victim of foul play, according to preliminary results of an autopsy Friday.

The cause and manner of death were not determined, however, and the investigation remains open.

Dr. Joel A. Perper, chief medical examiner of Broward County, Florida, said there was no indication of blunt-force trauma, asphyxiation or other physical trauma.

Perper said his office is awaiting results of toxicological and other tests, but there were no drugs in her stomach.

"There are a number of possibilities," he said, including natural causes, a drug reaction or some combination of causes.

Seminole Police Chief Charlie Tiger said no evidence suggests a crime occurred.

Tiger said no illegal drugs were found in Smith's hotel room. He said prescription drugs were found, but would not name them.

He said police were still analyzing surveillance tapes from the hotel, but so far had seen nothing unusual.

While the autopsy was taking place, a California judge ruled Smith's body must be preserved until at least February 20, when a hearing will be held to resolve a paternity dispute over the celebrity's 5-month-old daughter.

Superior Court Judge Robert Schneider's ruling came as new information surfaced about Smith's last days, during which she fell ill, according to sources.
