Natalie Wood's death certificate changed by authorities

The nature of Natalie Wood's demise, reclassified from "accidental" to "undetermined" in July, has been officially amended on the actress' death certificate, according to a revised document entered earlier this month.

Changes to the death certificate reflect 30-year-old questions surrounding Wood's drowning off Catalina Island in November 1981. 

How Wood got into the water, is one of the lingering questions. According to the amended document, that answer was never clearly established.

Sheriff's investigators  renewed the investigation last year, shortly before the 30th anniversary of the three-time Oscar nominee's death.

The case remains open, says LASD, noting that the coroner's office made the decision to amend the death certificate. Detectives placed a security hold on the document, and instructed coroner's officials to not discuss the case. 

The body of actress Natalie Wood was found in the ocean several hundred yards from the yacht "Splendour" where she had been spending Thanksgiving holiday with her husband, actor Robert Wagner, and actor Christopher Walken.
