No illegal drugs were found in Anna Nicole Smith's hotel room and there is no evidence that her death was a crime, police said at a press conference on Friday. "At this point no evidence has been revealed to suggest that a crime occurred. We have found no illegal drugs, only prescription medicines," said Charlie Tiger, Seminole Police Chief. "We are not releasing the names on those prescriptions. We have taken sworn statements from all the parties involved; everyone has cooperated fully." The Broward County, Fla., chief medical examiner, Dr. Joshua Perper, said that he found no pills in Smith's stomach, and that the final determination of the cause of death will require another three to five weeks. Perper said at the press conference that Thursday's death of the 39-year-old could have been caused by one of three reasons. The first, he said, is that it could be attributed "solely to natural causes." The second, "due to some medical and chemicals." And the third, "a combination of natural causes and medication. At this time we don't have the results that would allow us to make a final determination."
