"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. Investigators are now calling Wagner a ""person of interest"" in the 1981 death of his wife Natalie Wood. Mystery has swirled around Wood's death. It was declared an accident but police reopened the case in 2011 to see whether Wagner or anyone else played a role (AP File Photo)"
