Revealing what caused Anna Nicole Smith to die will "provide some resolution" in the matter, the Seminole, Fla., police said.

Joshua Perper, Broward County, Fla., medical examiner, said he would conduct a news conference as soon as Monday to announce what killed Smith. She died Feb. 8 in a Hollywood, Fla., hospital where she was taken after being found unresponsive in her hotel room.

Gary Bitner, Seminole Police Department spokesman, told the findings at the news conference "are going to be a significant announcement."

The spokesman added that the police, state attorney and the medical examiner's office have been working together and "it continues to be a non-criminal, unexplained death investigation."

Bitner said Perper's findings "are going to provide some resolution" in Smith's death.
