Despite new revelations about the death of Natalie Wood contained in an autopsy report released Monday, Los Angeles County Sheriff's Department sources said detective are far from ready to classify the case as a homicide.

The coroner's review found that the actress had several fresh bruises and scratches on her arm, wrist and neck that likely occurred before she landed in the Pacific Ocean and drowned.

One law enforcement source told The Times that detectives have been reexamining the case for more than a year and have gathered new evidence. But the evidence still leaves the death as "undetermined," said the source, who spoke on the condition of anonymity because the case was ongoing.

“This remains an ongoing investigation,” said Steve Whitmore, the Los Angeles County sheriff’s spokesman. “Yes this is a revelation to the public but this report was written in June 2012.”A sheriff's spokesman said his department has known the contents of the new autopsy for some time.

Whitmore said the Wood investigation became active again in November 2011 when the department received new information and the department asked the coroner to reexamine the case as part of that ongoing investigation.

“As in any death investigation, they remain ongoing until they reach a conclusion,” Whitmore said.

The new report, which was released on Monday, said that it could not verify that those injuries were caused by a fall off a dinghy or attempt to climb back into the boat, which has long been the theory of how she died on Nov. 29, 1981, off Catalina Island.

The Los Angeles County Sheriff's Department re-opened the case in November 2011 and the coroner later changed the cause of death from accidental to drowning and other undetermined factors.

In supporting that change, Dr. Lakshmanan Sathyavagiswaran filed a supplemental report dated June 15, 2012, that found that Wood died shortly after she entered the water.

"The location of the bruises, the multiplicity of the bruises, lack of head trauma, or facial bruising support bruising having occurred prior to the entry into the water," the supplemental report states.

"Since there are many unanswered questions and limited additional evidence available for evaluation, it is opined by this Medical Examiner that the manner of death should be left as undetermined."
