The autopsy report expected to disclose the cause of Anna Nicole Smith's death has been delayed due to new evidence that has come to light.

According to the Associated Press, Broward County medical examiner Dr. Joshua Perper said the autopsy tests have been completed and were supposed to be released late this week, but the Seminole Police, who have jurisdiction over the Seminole Hard Rock Hotel & Casino where Smith died, provided him with new evidence.

Gary Bitner, a spokesman for the Seminole Tribe and its police department, said the evidence provided by the tribe was turned over promptly.

"This is not delayed evidence this is just additional evidence that has come to light during the course of the investigation," Bitner said.

Perper's secretary said the autopsy would be released in the next week or two.

Smith, 39, died on February 8 after being found unconscious in her Florida hotel.

A day later, Perper released a preliminary autopsy that showed no immediate indication of a drug overdose and no sign of major external injuries on the former Playboy Playmate and Guess model.
