FILE - In this April 23, 1972 file photo, actor Robert Wagner and his former wife, actress Natalie Wood, pose at the Dorchester Hotel in London, England. Authorities amended Wood’s death certificate on Aug. 1, 2012 to reflect some of the lingering questions about how the actress died in the waters off Catalina Island in November 1981. The changes include altering her cause of death to “Drowning and other undetermined factors” and adding the statement “Circumstances not clearly established” to how Wood ended up in the water while on a yacht with husband Robert Wagner and actor and co-star Christopher Walken.
