The documents are altered by the L.A. County Coroner because some of the bruises on Wood's body were inconsistent with death by drowning.
Natalie Wood's death certificate has been altered. The documents initially ruled her passing as "accident," but now changes it to "undetermined." The change was made since some of the bruises on her body were inconsistent with death by drowning.
According to TMZ, the L.A. County Coroner filed the documents late last month and informed the late actress' family about the change on Friday, July 6. Authorities told the family they could not definitely prove whether her death was an accident or due to foul play, but they confirmed she did die from drowning.
Wood passed away at the age of 43 after falling into the water while boating with her husband Robert Wagner and actor Christopher Walken. Last year, the Los Angeles County Sheriff's Department announced they opened a new investigation into her death nearly 30 years after the incident.
