Police have delayed until at least Friday any details in the autopsy on the woman's body found at Laguna Lake on Monday.
Results of the autopsy and the woman's identification may be released - at the earliest - Friday, according to San Luis Obispo detectives.
It is unknown whether the woman had died of natural causes or was the victim of foul play. Police generally investigate such mysterious deaths as homicides until they can prove foul play was not involved.
A resident in the 1300 block of Oceanaire Drive, along the shore of Laguna Lake, called San Luis Obispo police around 3 p.m. Monday to report something suspicious. That caller declined to give his name to The Tribune when interviewed, saying only that he had seen something “unusual in the water.”

A firefighter who responded to the call waded into the water and found the body. The woman was found floating face down among reeds near the dock at the lake’s boat launch.
Police did not know Monday how long the body might have been in the water. Officers at the scene said there were no obvious signs of trauma or cause of death.
A detective with the county Sheriff-Coroner’s Department responded to assist in the investigation. Police said they likely would not know the identity of the body until after an autopsy is performed.
Investigators said they had not ruled out the possibility that the body was that of Shell Beach resident Stacie Jones. The 48-year-old woman went missing at Laguna Lake Park around 10 p.m. May 22.
Police said Jones had been at the park with a friend when she walked away toward Madonna Road and was not seen again. Police had searched the park extensively with the help of a CHP helicopter.
