The cause of Anna Nicole Smith's death remains unknown, the medical examiner who performed a preliminary autopsy said Friday.
But a number of prescription medications were found in her hotel room, police said. No illegal drugs were found in the room.
Broward County chief medical examiner Joshua Perper told reporters that it could take three to five weeks for further toxicology tests to determine the cause of the 39-year-old's untimely death.
"I am not a prophet, and I cannot tell you before the autopsy what I am going to find,'' he said.
Perper said no tablets or pills were found in Smith's stomach, suggesting she did not take a large amount of pills immediately before her death. He was also able to rule out death from physical injuries, such as blunt-force trauma, asphyxiation or other trauma.
Smith was found collapsed Thursday in a Florida hotel room by her nurse. She was taken to hospital where she was pronounced dead.
Speaking out Friday, Smith's mother said she believes drugs were behind the death of her daughter.
"I think she had too many drugs, just like Danny (Smith's late son),'' her mother, Vergie Arthur, told ABC's "Good Morning America'' on Friday. "I tried to warn her about drugs and the people that she hung around with. She didn't listen.''
"She was too drugged up,'' continued Arthur. "By the last interview I saw of her, she was so wasted.''
A news conference is scheduled for Friday afternoon, when preliminary results are expected from the autopsy.
"(Results) could come back quickly if it's natural causes," Access Hollywood's Tony Potts told Â鶹´«Ã½net on Friday.
"Also ... there's a toxicology report that usually takes a couple days... The toxicology report will be somewhat definitive (in determining if drugs were involved.)"
Smith had been travelling with her personal lawyer and companion Howard K. Stern and a private nurse.
"We don't know if this was characteristic of her travels... or because she had been suffering from flu-like symptoms in the last couple of days," said Lah.
Three men and a baby
In another strange twist, the husband of actress Zsa Zsa Gabor is saying he may be the father of Smith's infant daughter, Dannielynn.
Prince Frederic von Anhalt said Friday that he had a decade-long affair with Anna Nicole Smith, and in his words: "If you go back from September, she wasn't with one of those guys, she was with me.''
Dannielynn remains in the Bahamas, under care from the mother of Shane Gibson, the Bahamian immigration minister who was a close friend of Smith, reports People magazine.
Smith maintained throughout her final months that lawyer Howard K. Stern was the real father of her infant child. But Smith's former boyfriend Larry Birkhead says he's the father and has called for a paternity test.
A judge in Los Angeles denied an emergency motion by Birkhead Friday that requested DNA be taken from Smith's body immediately.
"Nothing was decided today... we have a full hearing on the 20th (of February)," his lawyer, Deborah Opri told reporters Friday. "My client wants custody of his child."
Smith's body will be preserved in Florida until a decision is made on Feb. 20.
Smith's attorney, Ron Rale, said he was shocked that Birkhead would initiate a motion so quickly after the death of his client.
Rale said Thursday that Smith was recently ill and depressed over the death of her 20-year-old son, Daniel, five months ago. He died in the Bahamas from an apparent drug overdose, just three days after Smith gave birth to her daughter.
